Joshua Boniface c8134d3a1c Fix several bugs in fence handling
1. Output from ipmitool was not being stripped, and stray newlines were
throwing off the comparisons. Fixes this.

2. Several stages were lacking meaningful messages. Adds these in so the
output is more clear about what is going on.

3. Reduce the sleep time after a fence to just 1x the
keepalive_interval, rather than 2x, because this seemed like excessively
long even for slow IPMI interfaces, especially since we're checking the
power state now anyways.

4. Set the node daemon state to an explicit 'fenced' state after a
successful fence to indicate to users that the node was indeed fenced
successfully and not still 'dead'.

Joshua Boniface 534c7cd7f0 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An additional item is that most format strings have been replaced by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.
