Joshua Boniface c76a5afd04 Avoid waits during node secondary
Waiting for the daemons to stop took too much time on some nodes and
could throw off the lockstep. Instead, leverage background=True to run
the systemctl os_commands in the background (when they complete is
irrelevant), stop the Metadata API first, and don't delay during its
stop at all.

Joshua Boniface b5f996febd Fix bugs for node flush for stop/shutdown/restart
Previously VMs in stop/shutdown/restart states wouldn't be properly
handled during a node flush. This fixes the bugs and ensures that the
transient VM states (shutdown/restart) are completed before proceeding,
and then avoids setting a stopped/shutdown VM to shutdown/auotstart.

Joshua Boniface afb0359c20 Refactor pvcnoded to reduce Daemon.py size
This branch commit refactors the pvcnoded component to better adhere to
good programming practices. The previous Daemon.py was a massive file
which contained almost 2000 lines of direct, root-level code which was
directly imported. Not only was this poor practice, but this resulted
in a nigh-unmaintainable file which was hard even for me to understand.

This refactoring splits a large section of the code from Daemon.py into
separate small modules and functions in the `util/` directory. This will
hopefully make most of the functionality easy to find and modify without
having to dig through a single large file.

Further the existing subcomponents have been moved to the `objects/`
directory which clearly separates them.

Finally, the Daemon.py code has mostly been moved into a function,
`entrypoint()`, which is then called from the `pvcnoded.py` stub.

An additional item is that most format strings have been replaced by
f-strings to make use of the Python 3.6 features in Daemon.py and the
utility files.
