This change extends the block device lvs attributes to allow creating
a volume which represents a thin pool, and to create volumes which are
allocated from this pool.

Currently there is a bug, that tries to detach the device from a
partition at the first try, without considering that there may be
other partitions and volumes on it. Ensure that the detach is done
properly, and add a test to ensure that this happens correctly.

Fixes-Bug: #1777861
Our sgdisk calls are putting extra double-quotes around the names of
partitions. This confuses sfdisk, which confuses growpart, which
confuses growroot ... and you don't get your partition grown for EFI
boot.
Ensure we just bunch arguments into the list directly (for Popen)
rather than string split and have to worry about quoting. Add a check
for this to our GPT unit test, extending it to include a space in the
name of the root partition.

This adds support for a GPT label type to the partitioning code. This
is relatively straight-forward translation of the partition config
into a sgparted command-line and subsequent call.
A unit test is added based on a working GPT/EFI configuration and the
fedora-minimal functional test is updated to build a single-partition
GPT based using the new block-device-gpt override element. See notes
in the sample configuration files about partition requirements and
types.
Documentation has been updated.

This small change avoids running fstrim on vfat partitions.
The mount order test-case has been updated to also test the mkfs
creation components, and the input config modified to have a vfat
partition to cover this path.

We intended to do an in-place sort of the mount-point list, but
sorted() returns a new list that wasn't captured. Move to the .sort()
function.
It seems the existing unit-test missed this. Add a new test taken
from the bug which does exhibit a sorting issue. Also added a
unit-test of just the comparitor for sanity.

Currently we pass a reference to a global "rollback" list to create()
to keep rollback functions. Other nodes don't need to know about
global rollback state, and by passing by reference we're giving them
the chance to mess it up for everyone else.
Add a "add_rollback()" function in NodeBase for create() calls to
register rollback calls within themselves. As they hit rollback
points they can add a new entry. lambda v arguments is much of a
muchness -- but this is similar to the standard atexit() call so with
go with that pattern. A new "rollback()" call is added that the
driver will invoke on each node as it works its way backwards in case
of failure.
On error, nodes will have rollback() called in reverse order (which
then calls registered rollbacks in reverse order).
A unit test is added to test rollback behaviour

As we add file-systems, add them to global state and check the labels
are uniqiue. Add a unit test and remove the old global value.
Bonus fixup to the length check, and a test for that too.

A couple of things going on, but I think it makes sense to do them
atomically.
The NodeBase.create() argument "results" is the global state
dictionary that will be saved to "state.json", and re-loaded in later
phases and passed to them as the argument "state". So for
consistency, call this argument "state" (this fits with the change out
to start building the state dictionary earlier in the
PluginBase.__init__() calls).
Since the "state" is a pretty important part of how everything works,
move it into a separate object. This is treated as essentially a
singleton. It bundles it nicely together for some added
documentation [1].
We move instantiation of this object out of the generic
BlockDevice.__init__() call and into the actual cmd_* drivers. This
is because there's two distinct instantiation operations -- creating a
new state (during cmd_create) and loading an existing state (other
cmd_*). This is also safer -- since we know the cmd_* arguments are
looking for an existing state.json, we will fail if it somehow goes
missing.
To more fully unit test this, some testing plugins and new
entry-points are added. These add known state values which we check
for. These should be a good basis for further tests.
[1] as noted, we could probably do some fun things in the future like
make this implement a dictionary and have some saftey features like
r/o keys.

This switches the code to use networkx for the digraph implementation.
Note that the old implementation specifically isn't removed in this
change -- for review clarity. It will be replaced by a base class
that defines things properly to the API described below.
Plugins return a node object with three functions
get_name() : return the unique name of this node
get_nodes() : return a list of nodes for insertion into the graph.
Usually this is just "self". Some special things like partitioning
add extra nodes at this point, however.
get_edges() : return a tuple of two lists; edges_from and edges_to
As you would expect the first is a list of node names that points to
us, and the second is a list of node names we point to. Usually
this is only populated as ([self.base],[]) -- i.e. our "base" node
points to us. Some plugins, such as mounting, create links both to
and from themselves, however.
Plugins have been updated, some test cases added (error cases
specifically)

This moves to a more generic config parser that doesn't have plugins
parsing part of the tree.
I understand why it ended up that way; we have "partitions" key which
has special semantics compared to others keys and there was a desire
to keep it isolated from core tree->graph code. But this isn't really
isolated; you have to reverse-engineer several module-crossing
boundaries, extras classes and repetitive recursive functions.
Ultimately, plugins should have access to the node graph, but not
participate in configuration parsing. This way we ensure that plugins
can't invent new methods of configuration parsing.
Note: unit tests produce the same tree -> graph conversion as the old
method. i.e. this is not intended to have a functional change.

Add a range of unit-testing for configuration parsing, graph
generation and mount-point generation. Unfortunately there's some
global variable hacks, and some stubs, but it's a start.
