To optimize memory consumption we where consuming
segment data during processing results from delete
query. Turns out that there is a chance that query will be
rolled-back if something will go wrong while reading
results. In such case its possible to delete pices but
object/segment will be still in DB.
This change removed piece deletion from problematic
place. Pieces are still deleted in batches but are not
limited at the moment. To avoid memory issues object
deletion batch was decreased.

This change adds a NOT NULL constraint to the created_at column in the segment table.
All occurrences of CreatedAt as a pointer are changed to non pointer version (metabase, segment loop, etc)

In case when number of deleted segments in a single
batch was multiplication of opts.DeletePiecesBatchSize it
was possible to finish deletion of objects to early.

It's possible that single object will have a lot of segments and
at the moment we are trying to collect all pieces at once and
send to storage nodes information about deletion. Such
approach my lead to using extensive amount of memory. This
change is handling this problem by calling DeletePieces
function multiple times with only part of pieces to delete for
a single call.

metabase has become a central concept and it's more suitable for it to
be directly nested under satellite rather than being part of metainfo.
metainfo is going to be the "endpoint" logic for handling requests.
