crimson/osd: use "ceph" for default cluster_name

for couple reasons:

* to avoid the pain to guess / update the cluster name when loading
  conf file. in the past, we use "ceph" as a fallback for the cluster
  name, which is in turn used as a meta name when expanding setting
  values containing "$cluster". so to ensure those settings continue
  working, we have to at least set cluster_name a safe value, and
  "ceph" is what we've been using.
* in
  http://lists.ceph.com/pipermail/ceph-users-ceph.com/2017-June/018519.html,
  we decided to drop the cluster_name support in deploy tools, and to
  keep this feature in code. so in the long run, we can assume
  new clusters will be all named "ceph".
* it's difficult to properly implement the feature to use "ceph",
  if no --conf option is specified, as, in Ceph, even the path pointing
  to conf file is allowed to contain "$cluster". so, to get it
  right, we need to update cluster name stored in options before
  reading the option files, this forces us to populate the setting
  twice when reading the settings from a conf file. or we could
  specialize the process, but i don't think it worthy of the
  efforts.

so i think we can just use "ceph" for the cluster name in crimson.

client: add mount/initialize states support and convert to RWRef

This will help us to break the big client_lock. Such as if we want
to add one separate lock for each inode, it will work like:

inode_lock.lock();
...
client_lock.lock();

client_lock.unlock();
...
inode_lock.unlock();

So we must get rid of the client_lock for all the "readers", which
must hold the client_lock from the beginning until the end.

client: add RWRef support

This is a common read/write reference framework, which will work
like a rw lock, for the readers/writers it won't hold the lock but
will increase the reference instead.

With this we can get rid of big locks in some use case, such as for
the Client.cc, in which such as for the file read()/write() it must
hold the client_lock at the begining until they finish, this will
make sure the _unmount() won't release the resources the read()/write()
are still using. With this it maks breaking the big client_lock to
be possible.

The usage: such as in Client.cc

Readers:

For the read()/writer(), etc, they will be work as "readers", in
the beginning they just need to check the state whether it satisfies
what the "readers" need to be, if not it will return directly, or
will increase the reference and continue.

Writers:

And for the _unmount(), as the "writer" in the beginning it will
just update the state to next stage first and when wait for all
the "readers" to finish. After the "writer" updating the state then
all the new comming "readers" will fail and return directly.

crimson/osd: spawn osd_op_params in do_write_op(). Fix overriding.

This commit deduplicates the `OpsExexuter::do_osd_op()` by moving
`std::optional`-typed `osd_op_params` instantiation to `do_write_op()`.
It also fixes an issue where `clean_regions` of `osd_op_params` were

crimson/osd: instantiate osd_op_params for every write.

This simplifies the logic of `OpsExecuter::flush_changes()` and
enables for moving the instantiation code to `do_write_op()` in
the future.

The performance impact seems negligible as the affected ops are
not the ones dominating in our expected workload (read/write, omap).
