osd: Remove override for osd_async_recovery_min_cost for mclock profiles

Overriding osd_async_recovery_min_cost as part of enabling a built-in
mclock profile has the undesirable side effect of peers not choosing
the correct async recovery targets if osds are using mixed schedulers
(this could happen during upgrades or if "debug_random" is set for
osd_op_queue config option). Due to the above, osds get into a
"choose_acting" loop during peering.

The solution is to remove the override of osd_async_recovery_min_cost.

Define config option "osd_mclock_profile" to specify the built-in profile
to enable.

Also, Set the number of op shards being used in the osd within the mclock
scheduler as well. This is necessary to calculate the per shard limits
within the mclock scheduler.

With the above information, enable the specified mclock profile by
calling the appropriate method to set the profile specific mclock
parameters and Ceph options.

Prior to enqueuing an op, the scheduler performs a calculation to scale
up or down the cost associated for the OpSchedulerItem. This calculation
is done based on the existing item cost, the max osd capacity provided
and an additional cost factor based on underlying device type(hdd/ssd).

osd: handle ceph specific config changes for the mclock scheduler

The below ceph parameters are set automatically
while enabling the mclock scheduler with a built-in profile.
The user in this case will not be able to modify these
ceph specific config options during runtime.

  a. osd_async_recovery_min_cost
  b. osd_recovery_max_active{_hdd,_ssd}
  c. osd_max_backfills
  d. osd_recovery_sleep{_hdd,_ssd,_hybrid}

If the custom profile is enabled for the mclock scheduler,
the user can modify these parameters.

client: wire up alternate_name

Here we're exposing a public Client::walk (aka path_walk) so that the
user can inspect dentries (not something normally possible in POSIX).
We're going to skip exposing such an interface in libcephfs since
there's no reason to do that (who would use it?) except for testing.
Instead, a follow-up PR will add Client tests (for the first time, yay!)
that will exercise this code.

Also, ideally we'd also expose alternate_name via readdir results but
that is a bit more complicated since dirents do not normally refer to
external memory. So, just rely on Client::walk for testing for now.

mds: fix alternate_name durability

This is a collection of fixes to Xiubo's prior work. Namely:

- Add new mds_alternate_name_max option to limit the size of
  alternate_name. Otherwise a Client could trick the MDS into creating
  an alternate_name of any size!

- Clean up how alternate_name is assigned to CDentry. In the general
  case, this should be assigned as part of creating the dentry. We want
  this value to be immutable for the life of the dentry. Even for the
  very special case of rename(2) where the destination dentry already
  exists.  We explicitly check (after discussion with Jeff) that the
  target dentry alternate_name already matches what the rename RPC is
  giving.

- The MDS is now properly journaling the alternate_name.

- The MDS rejoin phase is properly transmitting each dentry's
  alternate_name. I've discovered that this MMDSCacheRejoin message
  actually wasn't versioned which I've raised in a tracker [1]. In the
  mean time, we'll just bump CEPH_MDS_PROTOCOL as usual.

mds: add alternate_name feature support for dentries

This will support the "alternate_name" filename support, and will save
an alternate name for each dentry. This alternate name is not used in
path lookup or for any other usual file system purpose. The name is
simply an added blob of metadata on the dentry that is distributed to
clients so that "long" file names may be supported for clients which
require them. In the case of an fscrypt enhanced kernel mount driver,
the long name may be the cyphertext (exceeding FILENAME_MAX) of a long
file name.

Because this affects only files with long file names, the use of this
feature should be rare but could be common for some unusual
applications.

The client mount should check the CEPHFS_FEATURE_ALTERNATE_NAME feature
bit first to check whether the MDS has support for this feature or not.
The alternate_name is transmitted as part of the message payload in
MClientRequest when setting the alternate_name. The LeaseStat structure
in MClientReply contains the alternate_name.

When executing a metadata mutation RPC, the client will set the
alternate_name (if it exists) as part of the operation. The MDS will
pick that up and set it on the new or mutated dentry.

If the client has set the "encryption.ctx" attribute, the MDS side

The clients could use this flag to get to know whether the current
