This rather large test case tests the mirroring functions in an
end-to-end manner. It sets up the mirroring peers, enables mirroring on
directories and verifies that mirroring was set up by writing data and
verifying that data was propagated from site a to site b.
Ceph pacific is required to use cephfs mirroring and thus run this test.

Add functions EnableMirroringModule and DisableMirroringModule for
turning on an off the mirroring module at the ceph mgr.
This also adds the lower level EnableModule and DisableModule that take
a string parameter naming the module, and are the base for
EnableMirroringModule and DisableMirroringModule.

The fsConnect function is used by the tests to support getting a
data-path cephfs connection, in order to support those fs admin tests
that need to make changes in the file system directly. The new second
argument to the call allows for the cephfs connection to be made with a
non-default configuration.

Previously, the getFSAdmin function always fetched a cached (if
available) fsadmin instance set up for the default configuration of
ceph. This change makes getFSAdmin based on newFSAdmin a function
that always returns a new instance and allows a custom configuration
to be passed.
Otherwise, newFSAdmin works like getFSAdmin did previously, supporting
debugging via an environment variable.

The json key sent to retain snapshots on subvolume remove was misspelled
and had a dash in it rather than an underscore. Fix the incorrect key
and add a test, that needs to be able to run on version of cephfs w/o
snapshot retention, and verifies that flag does the correct thing.

Now that the new year has arrived this test assertion has started to
fail. This is because, although I anticipated the year would eventually
change and used GreaterOrEqual, the argument order is wrong. My excuse
is that I find the argument order in testify's Equal function confusing,
it causes me to assume other functions in testify are also confusing
(even when it's the "normal" order) and/or I copy and pasted from an
Equal line and didn't change the args (both are true!).
Instead of allowing any old year, we assume that the clocks where the
test are run are in sync enough that the current year is correct for
the assertion (thanks for the suggestion Sven).
Happy new year, go-ceph!

This flagSet type allows the user to also set the value of the retain
snapshots flag, something unique to subvolume removal (all others had
the force flag only).

To prepare for multiple flags types, we create a flagSet interface and
break out the functionality that was in Update into a per-type method
and then the common "merger" function.

Due to a new ceph nautilus the workflow test was breaking because the
existing code failed to anticipate the "subvolume uuid" in the path
to the snapshot data. This is the curse of writing code without anything
to test it against. I also add a very short delay just to give us
a chance to avoid issues in the future in case the snapshot creation
is not quite synchronous.

Apparently, this feature is being removed from all active ceph versions
and will not be present in future versions. Since we won't be able to
test it any more, and the api is provisional still, we just remove it
entirely.

This doesn't touch every call in cephfs admin, but does try to act like

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.

Rather than compile things in and out, which really should only be for
the client version of the ceph libs, add vars that tests can use to
check the server. Also, a "sentinel" test is added to make sure the
tests are being fed a version it understands.

Previously, I was sort of abusing the build tags system to just get our
tests working. That was incorrect because you could be building go-ceph
against nautilus libs but using an octopus server and vice versa. In
addition, I've learned that some of the snapshot and clone behaviors are
being changed as items are backported in ceph. This means that build
tags themselves are not good indicators of what a particular version of
ceph supports.
This patch is the first step to removing these restrictions and making
cephfs admin work more smoothly across more versions of ceph.

Add the new to octopus call for subvolume snapshot info. Two fields
appear to return strings "yes"/"no", so could possibly have been
converted to booleans. In the chance that other string values get
returned and simplicity I left them as strings. If we need to, we can add
convenience funcs to return bools later.

Add a SubVolumeInfo function that works like the `ceph fs subvolume
info` command. This function returns a SubVolumeInfo type from parsing
the response JSON.
In order to re-use the existing QuotaSize type, which is an interface
and thus can't be unmarshaled directly, we use a non-exported wrapper
type for the unmarshaling and then we fix up the BytesQuota field so
that users of the library don't need to directly deal with the quota
size placeholder type, which can unmarshal the value.

This clarifies what the size values are for when this interface is used
and hopefully clarifies what the size actually does to a subvolume. This
also generalizes the type a bit in preparation for it being used in
other upcoming functions.
