we want to know a lot more about what's going on during
the operation of the metainfo loop. this patchset adds
more instrumentation to previously unmonitored but
interesting functions, and adds metrics that keep track
of how far through a specific loop we are. it also
adds mon:lock annotations, especially to the metainfo
loop run task, which recently changed, silently broke
some queries, and thus failed to alert us to spiking
run time issues.

We were using two queries to delete one or more objects and its/their
segments in DeleteObjectExactVersion, DeletePendingObject, DeleteObjectLatestVersion,
DeleteObjectAnyStatusAllVersions,DeleteObjectsAllVersions.
This change delete objects and their segments in one query.

We have a use case for this in ListSegments. ListSegments is going to
return the EncryptedETag along with EncryptedKey and EncryptedKeyNonce.
It also must return the EncryptionParameters.
Since the EncryptionParameters are in the objects DB table, it would be
more efficient for ListSegment to avoid querying that DB table, but take
it from the SatStreamID.

This is one step for implementing the free tier:
* Change the default project limit from 10 to 3
* Move storage and bandwidth project usage limits from the metainfo
package to the console package (otherwise there is a cyclical
dependency, and metainfo doesn't use these values anyway)
* Change the default storage usage limit per project from 500gb to 50gb
* Change the default bandwidth usage limit per project from 500gb to 50gb
* Migrate the database so that old users and projects continue to have
the old defaults (10 projects/500gb usage)

We were deleting expired objects by directly executing a delete query.
With this change, we first select the objects to be deleted and then
delete them (as recommended by cockroachdb for deleting using a non indexed
column).

At some point we might try to change original segment RS values and set Pieces according to the new values. This change adds add NewRedundancy parameter for UpdateSegmentPieces method to give ability to do that. As a part of change NewPieces are validated against NewRedundancy.

At the moment we are trying to optimize deletion queries but its hard to verify deletion performance. Until we are sure that the queries are good we will just log errors instead shutting down whole satellite core.

If a non-nil value is read from created_at column of the segments table,
it will be set to the CreatedAt field if SegmentListItem.
Change-Id: I02691d8e11fad12c1b0e4c443bdebb568016ffe3
The created_at columns is first added without a default value to avoid
setting the current time to existing segments.

ListSegments loads all the segment data into memory, however this can
add up to a lot of data with inline segments and large objects.

Iterate over streams/segments rather than loading all of them into
memory. This reduces the memory overhead of metainfo loop.

For metainfo loop we need only some of Segment fields. By removing some of them we will reduce memory consumption during loop.
Change-Id: I4af8baab58f7de8ddf5e142380180bb70b1b442d
This method will be used only with metainfo loop and we need to customize query to consume less memory.

We want to read from DB only those fields that are used by metainfo loop so we need to remove most of fields from LoopObjectEntry.

Currently our metabase assumption is that it may contain arbitrary
bucket names and endpoint applies the naming constraints as it sees fit.
However by passing bucket_name as TEXT pg and crdb automatically try to
convert it to []byte, which may or not may work as intended... or in
some cases not work at all.
Cast all bucket name arguments to []byte to make it work.

We want to have custom loop iterator to avoid reading all object fields to reduce memory consumpion. This is first step to just rename existing iterator to IterateLoopObjects.

Currently the old encrypted keys may not match the path component

New metainfo loop can have memory issues when in one batch we will have object with many segments. This change limits number of batched segments to defined limit. Solution is not perfect as if we will have single object with extreme large segments count it can cross defined limit a lot. We need to prepare safer solution soon.

It looks that we cannot use root piece id as indicator if segment is inline as we have case in SLC satellite that inline segment have root piece id set. Pieces should be better thing to check.

Segments are not read in batches. For each batch of objects
we are reading all segments for those objects.

The subquery for DELETE FROM obects returns a stream_id field for filtering. Unfortunately stream_id is not indexed. This change removed the subquery from the CockroachDB delete bucket query.

When listing pending objects with prefix, the prefix should be prepended
to the EncryptedPath in satStreamID. Otherwise, listing multipart
uploads may display different UploadID than expected.

We need to keep empty inline segments as we did it with pointerDB because otherwise old uplinks after uploading data won't be able to download such file. To reduce number of empty inline segments on uplink side we need to implement skipping empty last inline segments for multipart upload.

ListAllBuckets could skip buckets when the total number of buckets
exceeds list limit. Replace listing buckets with looping directly

Until now we where using single RS per object but it turns out that we
need to be able to support RS per segment. We need to give uplink such information while downloading.
As an addition we are using RedundancySchemePerSegment flag for GetObject request to detect if
we should try to get RS from segment for this request response.

When there are concurrent refreshes to the cache and the entries are

only one is needed.

exists.
The current behavior is: everything is committed.

Old uplinks sends some additional information inside marshaled protobufs and we need to extract things like encryption parameters. Newer uplinks are passing it directly in request.

This adds AliasPieces run length encoding. On average it should

We wanto have single uplink branch for standard and multipart-upload satellite but some tests are using helper methods from multipart. This change adds methods used by uplink test.

We are checking if satStreamID is created in the last 48 hours. If it is
older we treat is as expired an fail to unmarshal it.
Since the satStreamID is also the Upload ID for multipart uploads, this
means that all calls fail for multipart uploads older than 48 hours.
Even aborting old multipart uploads is not possible.
To resolve this issue, we should stop checking satStreamID for
expiration.

Parts that have segment index gaps should be treated similarly how
