The SubVolumePath function maps the subvolume to a path from the root
of the cephfs, and works like `ceph fs subvolume getpath ...`.

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.

Some of the queries we need to make are not mgr commands but (still?)
mon commands. Extend the interface and helper funcs to support issuing
mon commands.

Removes some old reminder comments.
Adds doc comments with the keyword "Similar To" followed by block quoted

The environment variable to turn on tracing will now be parsed using
strconv.ParseBool rather than just a quick-n-dirty str compare.

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

When the ceph client code has not yet (asynchronously) gotten the mgr
map, it can return -EACCES when we run the MgrCommand function. We
before continuing with the test function to get the fsadmin we delay a
bit so that we are more likely to have the mgr map before continuing.
This change also fixes the caching of the fs admin.

Add a function for resizing a subvolume as well as types needed to
create the JSON command and parse the response JSON. The newSize
argument can be passed a numeric value (as a ByteCount) or the special
constant `Infinite` much like the ceph cli command. This is accomplished
using the interface type `NewSize`.

Allow the environment variable GO_CEPH_TEST_DEBUG_TRACE=yes to enable
tracing of the input & output json from the manager commands. This is
both useful for debugging the tests themselves and demonstrates the use
of something other than rados.Conn meeting the interface required by
FSAdmin.

These functions are not part of the cephfs APIs but will be based on the
various command-json features of the 'ceph' command line tool.
This change only adds a doc.go to stub in the package.
