Implement layer merge
...
A new command merges multiple snapshot/clone layers into one of them,
so merged layers can be deleted after this procedure

Implement CAS writes
...
From now on, reads will return the server-side object version numbers
and writes and deletes will have an additional "version" parameter
which, if set to a non-zero value, will be atomically compared with
the current version of the object plus 1 and the modification will
fail if it doesn't match.
This feature opens the road to correct online flattening of snapshot
layers and other interesting things.

Fix two potential read/write ordering problems (even though not yet seen in tests)
...
- Write operations could be 'stabilized' and previous versions could be
purged from OSDs before the removal of version_override and following
reads could potentially hit different version in EC pools
- Object was marked clean after completing the delete during recovery, so
reads could in theory hit a deleted version and return nothing

Delete objects only after a SYNC during rebalance in the non-immediate_commit mode
...
Previously OSDs could commit deletes before writes during recovery or rebalance
in the "lazy fsync" (immediate_commit=off) mode which could result in lost objects
