For improving the deletion performance we are shifting the
responsibility to delete the pieces of the object from Uplink to the
Satellite.
BeginDeleteObject was the first call to return the stream ID which was
used for after retrieving the list of segments and then get addressed
order limits for deleting the pieces (of each segment) from the storage
nodes.
Now we want the Satellite deletes the pieces of all the object segments
from the storage nodes hence we don't need anymore to have several
network round trips between the Uplink and the Satellite because the
Satellite can delete all of them in the initial BegingDeleteObject
request.
satellite/metainfo.ListSegments has been changed to return 0 items if
the pointer of the last segment of an object is not found because we
need to preserve the backward compatibility with Uplinks that won't be
updated to the last release and they rely on listing the segments after
calling BeginDeleteObject for retrieving the addressed order limits
to contact the storage nodes to delete the pieces.

Remove direct dependency on uplink.RSConfig, this simplifies
moving the config file without introducing weird dependencies.

Adds check to see if storage nodes are eligible to initiate
graceful exit, by checking their CreatedAt date and seeing if
their "age" is greater than the new config value:
NodeMinAgeInMonths
The default for this value is 6 months for now.

The endpoint listSegmentsManually method misses a check for the limit
parameter, otherwise it can return inconsistent results when it's 0 or
negative.
When 0 or negative, without the check, it returns no segments but also
that there isn't more segments and that isn't correct.
The function is only called from the Endpoint.ListSegments method and
the function cares to ensure that limit is always greater than 0, but if
the method doesn't check that a new future caller could misuse it and
provoke a bug.
Additionally:
* Documentation for the modified function has been written
* The part of the function that repeated the logic of the
Endpoint.getPointer method has been removed for using that method.
* Added logging before returning an internal error in
Endpoint.getPointer.

In satellite/accounting/rollup Service.RollupStorage we have a few
potential error scenarios that return time.Now(). Especially in the case
where we exit early because we have received 0 tallies since the *last*
rollup, this creates a potential race condition.
Between the time we call GetTalliesSince and realize it is empty, it's
possible a tally was inserted in that interval. As currently written we
are returning a latestTally time that excludes that tally.
We are currently protected because in Service.Rollup we don't save the
rollup unless we have populated the rollupStats. However, this change is
more correct and future-proof, because Service.RollupStorage should
always return a correct latestTally time, which in case of errors and
empty tallies, is the last successful tally.

Adds the KnownReliable method to Overlay Service that filters all nodes
from the given list to be only reliable nodes (online and qualified).
The method return []*pb.Node of reliable nodes. The pb.Node values are
ready for dialing.
The first use case is when deleting an object to efficiently dial all
reliable nodes holding a piece of that object and send them a delete
request.

Fixes a data race caused by not waiting for workers to finish
before shutting down. Currently this ended up failing logging
because it was closed when test tried to write to it.

this will allow us to inspect the type of `db.Driver()` on *sql.DB
connections to correctly differentiate between pg and crdb conns.
as a bonus, this moves all concerns about when to replace "cockroach://"
with "postgres://" out of view, letting the thin shim "driver" take care
of that.

Backstory: I needed a better way to pass around information about the
underlying driver and implementation to all the various db-using things
in satellitedb (at least until some new "cockroach driver" support makes
it to DBX). After hitting a few dead ends, I decided I wanted to have a
type that could act like a *dbx.DB but which would also carry
information about the implementation, etc. Then I could pass around that
type to all the things in satellitedb that previously wanted *dbx.DB.
But then I realized that *satellitedb.DB was, essentially, exactly that
already.
One thing that might have kept *satellitedb.DB from being directly
usable was that embedding a *dbx.DB inside it would make a lot of dbx
methods publicly available on a *satellitedb.DB instance that previously
were nicely encapsulated and hidden. But after a quick look, I realized
that _nothing_ outside of satellite/satellitedb even needs to use
satellitedb.DB at all. It didn't even need to be exported, except for
some trivially-replaceable code in migrate_postgres_test.go. And once
I made it unexported, any concerns about exposing new methods on it were
entirely moot.
So I have here changed the exported *satellitedb.DB type into the
unexported *satellitedb.satelliteDB type, and I have changed all the
places here that wanted raw dbx.DB handles to use this new type instead.
Now they can just take a gander at the implementation member on it and
know all they need to know about the underlying database.
This will make it possible for some other pending code here to
differentiate between postgres and cockroach backends.

exported methods.
* Log a forgotten internal error.
* Improve the documentation adding more and fixing some to fit to our

Return an error when misusing the endpoint method
'listSegmentsFromNumberOfSegments' because there is the method
'listSegmentsManually' for being used when the number of segments is
less or equal than 0.
If we don't return an error on `listSegmentsFromNumberOfSegments` we
would realize that we have a bug much more later than returning an error
because the clients wouldn't receive an error and would receive an empty
list, making them to wonder what they are doing wrong to receive 0
results before they realize that they could be in front of a bug.
This commit also renames the function to be plural as "numberOfSegments"
parameter and the test function which missed also the end 's'.

for storj-sim to work, we need to avoid schemas in cockroach urls
so we have storj-sim create namespaced databases instead of schemas
and we have the migrate command create the database in the same way
that it would create a schema for postgres. then it works!
a follow up commit will move the creation of the database/schemas
into storj-sim's setup step so that we can avoid doing these icky
creations during normal migration calls. it will also make the
pointerdb have an explicit call to migrate instead of just doing
it every time it's opened.

satellitedb migration tests ran against multiple base versions, however after the merging all the steps the base versions didn't exists anymore - which meant none of the migration tests were actually running.
