21717262ec [#2016] shard: Check meta first on Get 
`meta` should prevent returning removed objects (`GCMark` and `TS` relations
are `meta` abstractions).

74ec71446f [#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).

2849e465f9 [#1699] meta: Do not return SplitInfoError on Delete 
It is not an error: removing virtual object is expected and should be just
skipped. Getting a virtual object with `raw` flag is considered as an
impossible action, all the virtual objects removals will be handled via
their children's removals implicitly.

d8d3588e1b [#1996] engine: Always select proper shard for a tree 
Currently there is a possibility for modifying operations to fail
because of I/O errors and a new tree to be created on another shard.
This commit adds existence check for modifying operations.
Read operations remain as they are, not to slow things.
`TreeDrop` is an exception, because this is a tree removal and trying
multiple shards is not an unwanted behaviour.

5cf75404dc [#1818] metabase: Add UpdateStorageID operation 
By default writecache puts the whole object to update storage ID.
This logic comes from the times when we needed to put objects
in the metabase by the writecache itself. Now this is done by the
blobstor at unmarshaling objects during flush only to update storage ID
is an overkill.
