We need to return success if we get a dup command. Simply check whether
the fs is already enabled with the same pools and name.

This was broken at ea68b93723. We ended
up calling wait_pending_front() when pending list was empty.
This commit also moves the need_to_wait check to a different place,
where we actually throttle (and not just drain completed IOs).

(cherry picked from commit f9f2417d7d)
Treat rbd_default_{format,order,stripe_unit,stripe_count} as defaults for
the usual arguments for specifying those properties.
librbd::create() is affected by rbd_default_format, so we need to
explicitly override it if --image-format is set. The rest of the
parameters are passed explicitly when they are used, so their rbd_default
equivalents don't matter.

We want to make sure the daemon runs in its own systemd environment. Check
for systemd as pid 1 and, when present, use systemd-run -r <cmd> to do
this.

This fixes the size of some integers that are visible in the network
protocol. There should be no change for machines where sizeof(int) ==
4.

This clarifies how to deal with layouts in CephFS
using vxattrs. We can point people here if they
ask what they should use instead of the deprecated
`cephfs set_layout`.
