Sébastien Han 8dfa99e01d ceph: rework multiple filesystem support 
The upcoming Rook release 1.6 will support Ceph Pacific which introduces
stable support for multiple Ceph Filesystems in the same cluster. So we
now allow the creation of multiple Filesystem if the release is Pacific.

Also, we remove the Operator config flag which was not necessary.

Here I have 2 filesystems:

```
[root@rook-ceph-tools-6b4889fdfd-vncck /]# ceph fs ls
name: myfs, metadata pool: myfs-metadata, data pools: [myfs-data0 ]
name: myfs2, metadata pool: myfs2-metadata, data pools: [myfs2-data0 ]
```

```
  cluster:
    id:     cc747950-589a-4862-bad2-ff7de1217b1a
    health: HEALTH_WARN
            mons a,b,c are low on available space
            6 pool(s) have no replicas configured

  services:
    mon: 3 daemons, quorum a,b,c (age 2d)
    mgr: a(active, since 2d)
    mds: myfs:1 myfs2:1 {myfs2:0=myfs2-b=up:active,myfs:0=myfs-b=up:active} 2 up:standby-replay
    osd: 3 osds: 3 up (since 2m), 3 in (since 6d)

  data:
    pools:   6 pools, 717 pgs
    objects: 44 objects, 4.2 KiB
    usage:   46 MiB used, 90 GiB / 90 GiB avail
    pgs:     717 active+clean

  io:
    client:   1.8 KiB/s rd, 4 op/s rd, 0 op/s wr

  progress:
    Global Recovery Event (45s)
      [===========================.]
