cephfs: add various error strings for command validation

Browse Source 
Compared to previous version of the error strings, this change
depend on error strings like ENOENT, EEXIST, EINVAL..etc
The format of the error strings change in different cluster versions
and the error code return should not change. This also add extra
error strings for snapshot and clone operation outputs
