Piece deletion service was using KnownReliable method from
overlaycache to get nodes addresses to send delete request.
KnownReliable was always hitting DB because this method was
not using cache. This change is using new DownloadSelectionCache
to avoid direct DB calls.
Change is not perfect because DownloadSelectionCache is not as
precise as KnownReliable method and can select few more nodes
to which we will send delete request but difference should be
small and we can improve it later.

Currently slower storagenodes can slow down deletion queue.
To make piece deletion faster reduce the maximum time spent in
either dialing or piece deletion requests.
With this change:
* dial timeout is 3s
* request timeout is 15s
* fail threshold is set to 10min
Similarly, we'll mark storage node as failed when the timeout occurs.
The timeout usually indicates that the storagenode is overwhelmed.
Garbage collection will ensure that the pieces get deleted eventually.

We are not using the benchmark results for anything, they are mostly
there to ensure that we don't break the benchmarks. So we can disable
CockroachDB for them.
Similarly add short versions of other tests.
Also try to precompile test/benchmark code.

It's safer to create new connection pool for piece deletion
only if dialer have no existing pool assigned.

We want to enable connection pool for piece deletion to avoid
doing multiple SSL hanshakes to SN while massive deletion process.

Satellites set their configuration values to default values using
cfgstruct, however, it turns out our tests don't test these values
at all! Instead, they have a completely separate definition system
that is easy to forget about.
As is to be expected, these values have drifted, and it appears
in a few cases test planet is testing unreasonable values that we
won't see in production, or perhaps worse, features enabled in
production were missed and weren't enabled in testplanet.
This change makes it so all values are configured the same,
systematic way, so it's easy to see when test values are different
than dev values or release values, and it's less hard to forget
to enable features in testplanet.
In terms of reviewing, this change should be actually fairly
easy to review, considering private/testplanet/satellite.go keeps
the current config system and the new one and confirms that they
result in identical configurations, so you can be certain that
nothing was missed and the config is all correct.
You can also check the config lock to see what actual config
values changed.

Make metainfo.RSConfig a valid pflag config value. This allows us to
configure the RSConfig as a string like k/m/o/n-shareSize, which makes
having multiple supported RS schemes easier in the future.
RS-related config values that are no longer needed have been removed
(MinTotalThreshold, MaxTotalThreshold, MaxBufferMem, Verify).

This PR fixes a deadlock that can happen when the number of piece
deletion requests is different from the distinct node count from those
requests. The success threshold should be based on the number of nodes
instead of the amount of requests

This PR adds a limiter on the amount of concurrent objects deletion can be handled so
we don't run out of memory.

This runs each benchmark for one iteration to ensure that they are
valid. Unfortunately, it does not give any useful metrics as output.

Before the deleter would close its done channel once, so if additional
tests shared a storagenode, even if not in parallel, the later waits
would not work properly. This fixes that problem.

When running testplanet tests, mark storagenode peer PieceDeleter as in

There was a race in the test code for piece deleter, which made it
possible to broadcast on the condition variable before anyone was
waiting. This change fixes that and has Wait take a context so it times
out with the context.

To improve delete performance, we want to process deletes asynchronously
once the message has been received from the satellite. This change makes
it so that storagenodes will send the delete request to a piece Deleter,
which will process a "best-effort" delete asynchronously and return a
success message to the satellite.
There is a configurable number of max delete workers and a max delete
queue size.

Currently it was possible that PopAll returns 1010 items, then
makes one RPC call with 1000 items, then RPC call 10 items. Meanwhile,
there have been added 500 new items added to the queue.
This change ensures that we pull items from the queue early and
try to make rpc batches as large as possible.

Instead of providing the database from outside to testplanet create it
inside and then allow wrapping and modifying it. This is more convenient
to use.

This adds a piece deletion handler that has debounce for failed dialing
and batching multiple jobs into a single request.
Change-Id: If64021bebb2faae7f3e6bdcceef705aed41e7d7b
To handle concurrent deletion requests we need to combine them into a
single request.
To implement this we introduces few concurrency ideas:
* Combiner, which takes a node id and a Job and handles combining
multiple requests to a single batch.
* Job, which represents deleting of multiple piece ids with a
notification mechanism to the caller.
* Queue, which provides communication from Combiner to Handler.
It can limit the number of requests per work queue.
* Handler, which takes an active Queue and processes it until it has
consumed all the jobs.
It can provide limits to handling concurrency.
