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.

The created_at columns is first added without a default value to avoid
setting the current time to existing segments.

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.

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
encoding. Change the iterator such that the prefixes handle arbitrary
byte sequences.

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.

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.

When there are concurrent refreshes to the cache and the entries are
missing, it could end up causing multiple database calls, even though
only one is needed.

adds tests to BeginObjectNextVersion and BeginObjectExactVersion
to check the behavior when an older or a newer committed version
exists.
The current behavior is: everything is committed.

This adds AliasPieces run length encoding. On average it should
make our pieces encoding:
repair=50,optimal=85,total=90 152.0 bytes
repair=16,optimal=37,total=50 65.4 bytes

We will add a cache to nodes, so using completely random nodes wouldn't
show the actual performance.

We need to keep an inmemory cache to avoid lookups into aliases table.
This adds the inmemory state of the cache.

This is first step in supporting node aliases. It adds a table
that automatically assigns aliases to nodes inserted into the table.

We need this method to fix repairing pending objects. In another PR, it
will replace the GetObjectLatestVersion + GetSegmentByPosition calls
that are currently executed.

Comparing the result from a subquery with the "IN" operator instead of
"=" makes a huge difference in the execution time of the SQL query on
CockroachDB.

Parts that have segment index gaps should be treated similarly how
multipart objects are, because direct calculation of the segment does
not work.

In some cases we need to set encryption parameters later, with CommitObject method. This change makes Encryption optional with BeginObject* methods and mandatory with CommitObject if not set earlier.
