[ #734 ] shard: Fix Delete method
...
Due to the flushing data from the writecache to the storage
and simultaneous deletion, a partial deletion situation is possible.
So as a solution, deletion is allowed only when the object is in storage,
because object will be deleted from writecache by flush goroutine.

[ #2116 ] metrics: Track physical object capacity in the container
...
Currently we track based on `PayloadSize`, because it is already stored
in the metabase and it is easier to calculate without slowing down the
whole system.

[ #2208 ] engine: Log time-consuming shard operations
...
Currently the only way to tell whether `evacuate/set-mode` is finished
is to set a very big timeout and _hope_ that the operation will finish.
In this commit we add INFO logs for such operations which should
simplify the life of an administrator.

[ #2200 ] shard: Fix blobstor obj fetching
...
In the previous implementation any non-nil error that preceded object
fetching from blobstor led to iterating over every storage (in other words,
no storage ID information was taken into account). Now storage ID is
skipped only if metabase (storage ID source) returns any error.

[ #2165 ] pilorama: Optimize TreeApply
when used for synchronization
...
Because synchronization _most likely_ will have apply already existing
operations, it is much faster to check their presence in a read
transaction. However, always doing this will degrade the perfomance
for normal `Apply`. And, let's be honest, it is already not good.
Thus we add a separate parameter which specifies whether this logic is
enabled.

`meta` should prevent returning removed objects (`GCMark` and `TS` relations

[ #2167 ] shard: Do not use write-cache by default in Head
...
Both `meta` and `write-cache` are expected to have a fast underlying disk,
so it does not seem like an optimisation. Moreover, `write-cache`'s `Head`
is a `Get` with payload cutting, it _must_ use more memory for no reason
(`meta` was created for such requests). Also, `write-cache` does not allow
performing any "meta" relations checks (such as locking, tombstoning).
