Current metainfo.ListObjects implementation is using metabase iterator to list objects.
In the non-recursive case, it used to retrieve all the corresponding rows and then discarded the entries that did not fit the listing request.
This can lead in some edge cases (each prefix contains more than batchsize objects/sub-prefixes) to make unecessary calls to the db.
This change defines the metabase.ListObjects and aims at retrieving only prefixes (but not objects under it) and objects by modifying the SQL query.
In this version, it is not optimized on the database side. Cockroach will still have to go through all rows under a prefix, so there is still room for improvement.
metainfo.ListObjects is not currently using this method as we would like to assess its performance on the QA satellite first.

* begin methods for move and copy are now using GetObjectLastCommitted

* results from begin move and copy operation contains now version to
be able to map object correctly with finish operation
* begin methods are putting version into satellite stream id and
finish methods are using this version as parameter instead hardcoded

We noticed that in the system we have undeleted very old pending
objects. General rule is to delete them after some inactivity. Turns
out that all those objects are objects migrated to metabase from
previous DB schema. During this migration we didn't set
zombie_deletion_deadline to any value.
This change takes into account pending objects with zombie deletion
deadline set to nil during zombie deletion process.
I also checked accross all production satellites and youngest pending
objects with nil zombie_deletion_deadline are from 2021 so it is safe
to delete them.

Don't terminate the expired objects loop or the zombie objects loop when
there is a DB error when selecting the objects for deleting them because
it isn't critical and the loops will pick them up again in the next
iteration.
The exception is if the DB rows scan method returns an error because
that's a symptom of the passed arguments to the method don't match with
the columns order, number, or type of the query, or there is invalid
data in the DB.
Don't also terminate these loops if the there is a DB error when
deleting the objects because the loops will pick them up in the next
iteration.
Because we don't return those errors now for not terminating the loop,
we have to log them.

BeginObject methods will set metadata always (niled or not niled).
One additional improvment for metadata fields was introduced and it's
validating fields as optional if EncryptedMetadata was not set.
This change currently doesn't have any implications and it's a base for
other changes. Metadata is not set with BeginObject metainfo endpoint
yet.

Multipart upload limits added. Last part has no size limit.
Max number of parts: 10000, min part size: 5 MiB

this is so that multipart upload allows overwriting parts. our
consistency model is more relaxed because part overwrites
won't be atomic if they consist of multiple segments, but at
least this allows overwriting at all.

This change introduce problems with server side move so
let's revert it for now. Problem was found when latest
version of storj/storj was used in uplink tests.
This reverts commit 1ef06fae99.

We were using mixed types for nonce fields. Protobuf
have storj.Nonce, metabase have []byte. This change
is a refactoring to have everywere its possible only
storj.Nonce.

We were manually converting ObjectKey fields to []byte to use it with
SQL query but we can just implement Value method to convert it automatically.

We would like to verify if zombie object/segment works fine.
We need some metric for that. Figuring out number of deleted
objects is harder so let's for that later.

Currently loops wait for the coalesce duration for TriggerWait.
Let's skip the coalesce when we trigger it manually.

server-side move extended with moving between buckets, for this reason
we change bucket name for object in db.

Not all errors from RunOnce can be retried. The context can be cancelled
with several different errors, e.g. timeout. Ensure we stop the loop
when context has errored, because none of the queries will succeed
when it has failed.
