turns out portable sed is hard: it has to work with both
linux and bsd sed, etc. instead, use a really really basic
bash script and a temporary file. this should be much less
likely to cause issues on a wide range of machines.

Transactions in our code that might need to work against CockroachDB
need to be retried in the event of a retryable error. The transaction
helper functions in dbutil do that automatically. I am changing this
code to use those helpers instead.
I also fleshed out consoledb_test.go to do actual inserts and gets to
make sure things were working correctly.

Disqualifies a node when the node fails to complete a graceful
exit.
Adds a new DisqualifyNode method to the overlay cache, since there
wasn't an existing method to disqualify a node but do nothing else
to its stats.
Adds checks to existing tests to make sure that a storage node that
fails a graceful exit is marked as disqualified in the overlay
cache.

crdb.ExecuteTx is great, but I don't think it will work right with
PostgreSQL. It works by way of cockroach savepoints, which allows
it to react to retryable errors, whereas tx.Commit() doesn't. But
I don't think PostgreSQL savepoints work exactly the same way. I'm not
100% sure, but it doesn't seem worth the risk.
So, I'm switching one case here to use the new dbutil.WithTx instead,
which will use crdb.ExecuteTx if appropriate. The other case doesn't
need a transaction at all.

Remove starting up messages from peers. We expect all of them to start,
if they don't, then they should return an error why they don't start.
The only informative message is when a service is disabled.
When doing initial database setup then each migration step isn't
informative, hence print only a single line with the final version.
Also use shorter log scopes.

We don't want slowloris nodes to be able to indefinitely block
up the satellite, so add a timeout. Some monitoring inspection
showed the largest success times being on the order of 30s, so
a 1min timeout should be sufficient to kill the misbehaving nodes.

As per discussed we decided to rate limit how fast we iterate through
the metainfo database in the metainfo loop. This puts in place a
mechanism for rate limiting and burst limiting if need be in the future.
The default for this rate limiting is still no limits so it stays the
same as our previous functionality.

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.

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.
