qa/workunits/rbd: make continuous export-diff test actually work

The current version is pretty useless:

- "rbd bench" writes the same byte (0xff) over and over again, so
  almost all checksumming is in vain
- snapshots are taken in a steady state (i.e. not under I/O), so no
  race conditions can get exposed
- even with these caveats, it's not wired up into the suite

Redo this workunit to be a reliable reproducer for the issue fixed
in the previous commit and wire it up for both krbd and rbd-nbd.

librbd: stop passing IOContext to image dispatch write methods

This is a major footgun since any value passed e.g. at the API layer
may be stale by the time we get to object dispatch.  All callers are
passing the IOContext returned by get_data_io_context() for their
ImageCtx anyway, highlighting that the parameter is fictitious.

Only the read method can meaningfully take IOContext.

librbd: use an up-to-date snap context when owning the exclusive lock

By effectively moving capturing of the snap context to the API layer,
commit 1d0a3b17f590 ("librbd: pass IOContext to image-extent IO
dispatch methods") introduced a nasty regression.  The snap context can
be captured only after exclusive lock is safely held for the duration
of dealing with the image request and even then must be refreshed if
a snapshot creation request is accepted from a peer.  This is needed to
ensure correctness of the object map in general and fast-diff states in
particular (OBJECT_EXISTS vs OBJECT_EXISTS_CLEAN) and object deltas
computed based off of them.  Otherwise the object map that is forked
for the snapshot isn't guaranteed to accurately reflect the contents of
the snapshot when the snapshot is taken under I/O (as in disabling the
object map may lead to different results being returned for reads).

The regression affects mainly differential backup and snapshot-based
mirroring use cases with object-map and/or fast-diff enabled: since
some object deltas may be incomplete, the destination image may get
corrupted.

This commit represents a reasonable minimal fix: IOContext passed
through to ImageDispatch is effected only for reads and just gets
ignored for writes.  The next commit cleans up further by undoing the
passing of IOContext through the image dispatch layers for writes.

librbd: localize snap_remove op for mirror snapshots

A client may attempt a lock request not quickly enough to
obtain exclusive lock for operations when another competing
client responds quicker. This can happen when a peer site has
different performance characteristics or latency. Instead of
relying on this unpredictable behavior, localize operation to
primary cluster.

qa/suites/rados: remove rook coverage from the rados suite

The rook team relies on a daily CI system to validate
rook changes. It doesn't seem that the teuthology tests
are maintained, so it makes sense to remove them from the
rados suite.

By removing this symlink, rook test coverage will remain
in the orch suite, and coverage will only be removed from the
rados suite.
