api: cephfs: more checks on fs create

Browse Source 
namely if the fs is already existing, and if there is currently a
standby mds that can be used for the new fs
previosuly, only one cephfs was possible, so these checks were not
necessary. now with pacific, it is possible to have multiple cephfs'
and we should check for those.
