Add retain service on storagenode. This service runs retain jobs that have been queued by the storagenodes. Rather than running retain jobs during the grpc Retain() call, the grpc call queues a retain job to the retain service and returns immediately afterwards, removing a significant bottleneck in garbage collection.
* add cache, update cache w/piece create/delete
* add service w/loop to cache to recalculate space used cache
* add piecestore cache to other sn svcs to use
* add table to persist the total space used
* rm cache where not needed
* rm stuff from sn svcs
* start fixing tests, changes per comments
* update commits
* add unit tests
* fix commiting before we write header bytes
* fix cache create test
* copy cache map, add started back to recalc
* fix test
* add test, update comments
Deprecate the pieceinfo database, and start storing piece info as a header to
piece files. Institute a "storage format version" concept allowing us to handle
pieces stored under multiple different types of storage. Add a piece_expirations
table which will still be used to track expiration times, so we can query it, but
which should be much smaller than the pieceinfo database would be for the
same number of pieces. (Only pieces with expiration times need to be stored in piece_expirations, and we don't need to store large byte blobs like the serialized
order limit, etc.) Use specialized names for accessing any functionality related
only to dealing with V0 pieces (e.g., `store.V0PieceInfo()`). Move SpaceUsed-
type functionality under the purview of the piece store. Add some generic
interfaces for traversing all blobs or all pieces. Add lots of tests.
* storagenode/piecestore: track live requests together
Change-Id: I9ed44e4484b97bcbe076c222450c3449fe8b1075
* show grpc status codes in monkit failures

* storagenode/piecestore: Unexport endpoint method
Make an exported endpoint method to be unexported because it's only used
by the same package and makes easy to change without thinking in
breaking changes.
* uplink/ecclient: Use structured logger
Swap sugared logger by the normal structured logger for having the full
stack traces of the error in the debug message.
* storagenode/piecestore: Send gRPC error codes upload
Refactoring in the storagenode/piecestore to send gRPC status error codes
when some of the methods involved by upload return an error.
The uplink related to uploads has also been modified to retrieve the
gRPC status code when an error is returned by the server.
* rename pkg/linksharing to linksharing
* rename pkg/httpserver to linksharing/httpserver
* rename pkg/eestream to uplink/eestream
* rename pkg/stream to uplink/stream

* rename pkg/auth/signing to pkg/signing
* rename pkg/storage to uplink/storage
* rename pkg/accounting to satellite/accounting
* rename pkg/audit to satellite/audit

* rename pkg/overlay to satellite/overlay
* rename pkg/datarepair to satellite/repair
If we verify that the size matches reality, we can then expect to use
the filesystem to store the piece size as used in the signed PieceHash
from the uplink. Otherwise, the uplink might send a garbage size value,
leaving the storagenode with no good way to verify the uplink signature
on the piece at a later date.
Also fix the code in uplink/piecestore/ so that it sends a valid size,
because it was being rude and sending 0.
What: add monkit.Task to a bunch of functions that are missing it
Why: this will significantly help our instrumentation, data collection, and tracing about what's going on in the network
* first round cleanup based on go-critic
* more issues resolved for ifelsechain and unlambda checks
* updated from master and gocritic found a new ifElseChain issue
* disable appendAssign. i reports false positives
* re-enabled go-critic appendAssign and disabled lint check at code line level
* fixed go-critic lint error
* fixed // nolint add gocritic specifically
