This commit is the minial version of the work, contained entirely

were ideas like e.g. adding cache tiering back experimental feature

crimson/os/seastore: don't set INVALID extents to CLEAN when reading
extents

CLEAN_PENDING extents may be invalidated before read completes:

1. transaction A retired an laddr, which lead to a RetirePlaceHolder in
   Cache
2. transaction B try to read that extent, and replace A's
   RetirePlaceHolder with it;
3. transaction A commits and invalidate that extent;
4. transaction B complete reading that extent;

In this case, we shouldn't set the extent's state to CLEAN

crimson/osd: Introduce with_head_and_clone_obc()

In continuation to 7ca2690be956a36f61c7729946b94ccd970dd9c7:
Now that the head ref is no longer a member of obc, we need a new
substitute way to get the head when needed.

When loading a clone object, the head object is loaded
first (See with_clone_obc). Therefore we can make use of this design
to move the loaded head forward to the relevant func (See with_head_and_clone_obc).
Usually, we wouldn't need to make use of both the head and the clone obc in the
same function. However, SnapTrimObjSubEvent::remove_or_update is an abnormal usage.

Note: We want to avoid holding any unneeded references to obcs
to allow the obc_registery to evict no longer valid obc.
Therefore, with_obc() which references only a single obc is the
preferred entry point for loading obcs.

crimson/osd: Remove head memeber from ObjectContext

Before this patch, ObjectContext had a head member which was used
to get the head obc of a clone object.
This member caused the head object to being referenced while
attempting to 'clear_replica_obc' (Since we only evict un-referenced
obc from the obc_registery).
This mechanism, of obtaining the head, is no longer needed since
'with_clone_obc' loads the head object context first (using
oid.get_head).

In this commit, head is removed from ObjectContext class and users
are removed as well.
