If the ceph cluster we're testing against supports more then one
fs our tests shouldn't fail. Update the tests to ensure a cephfs
exists as expected but don't assume it's the only one (or that
it's the first one returned).

It appears the JSON being returned from `ceph fs status` has changed.
The field returning the mds version was previously "just" a string.
Now its a more complex thing. This of course breaks the old version
of the go code which is statically typed to expect a string.
In order not to break backwards compatibility we replace the object
used for parsing the JSON with a private object that has a custom
unmarshaller function for the mds version field. If it sees the string
it uses the string. Otherwise, it looks for this new structure and,
if possible, extracts the version string from the first item.

Luminous and mimic have not been supported for a few releases now.
There's no need to keep these build tags any more.

Now that we have shared support working with "command json" we attempt
a minimal conversion, using aliases where appropriate, to the
new commands.Response type.

For users who need to know the pools (by name) as well as the files
systems, we add ListFileSystems which is similar to 'ceph fs ls', rather
than the existing ListVolumes as that function is simlar to 'ceph fs
volume ls' and that does not return pool information.

Return not implemented errors when "older" versions of ceph return
formatted text for output instead of JSON, even tho we asked for json.

The response type simplifies the error handling as a "pipeline" of
checks that are applied one after another.

The EnumerateVolumes function returns a list of Name & ID pairs,
to identify the file systems in the cluster. The enumeration is based
on `ceph fs dump` like JSON, but for implementation only. The dump
feature itself is not currently exported in a raw form.

The volume status command does not appear to be able to return JSON
on nautilus. Disable it on anything other than octopus for now.
