In preparation for acquiring the xlock on the directory inode, the MDS
must journal a few events before continuing on with the setvxattr. This
can cause significant delays in the volumes ceph-mgr module which needs
to regularly enable this vxattr from multiple code paths. We could cache
in that module whether the vxattr is set but it's also pretty easy to
adjust the MDS to acquire a rdlock on the directory to check if the
subvolume flag is already set. That is much lighter weight and the lock
is generally readily available.

crimson/os: synchronize producers with consumers in AlienStore's queues.

Some time ago we replaced the single, `boost::lockfree`-based queue
in `ThreadPool` with the in-house, lockish `ShardedWorkQueue` vector.
Unfortunately, pushing into such queue isn't synchronized with
consuming from it -- the former happens without locking the `mutex`.
As the underlying primitive behind `ShardedWorkQueue::pending` is
plain `std::deque`, it's unsafe to operate that way in multi-thread
environment. Indeed, weirdly looking crashes have been spotted at Sepia:

This fix introduces the synchronization to the `push_back()` method of
`ShardedWorkQueue`. The side effect is that it may stall the reactor.
Therefore, a follow-up change that switches to e.g. `boost::lockfree`
is expected.

crimson/common: extract parallel_for_each_state out

if `parallel_for_each_state` is defined as a nested class in errorator,
clang fails to compile it:

../src/crimson/common/errorator.h:716:47: error: no class named 'parallel_for_each_state' in 'errorator<AllowedErrors...>'
    friend class errorator<AllowedErrors...>::parallel_for_each_state;
                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^

and the forward declaration does not help. so we have to extract it
out of the errorator. to speed up the compilation, it is moved into
errorator-loop.h. its name mirrors `include/seastar/core/loop.h`.

we could extract the `errorator<>::parallel_for_each()` out as well,
as its return type can be deduced from the type of Iterator and Func.
