Joshua Boniface 2ee52e44d3 Move Ceph cluster health reporting to plugin
Also removes several outputs from the normal keepalive that were
superfluous/static so that the main output fits on one line.

Joshua Boniface 5942aa50fc Avoid raise/handle deadlocks
Can cause log flooding in some edge cases and isn't really needed any
longer. Use a proper conditional followed by an actual error handler.

Joshua Boniface 8d0f26ff7a Add additional kb_ values to OSD stats
Allows for easier parsing later to get e.g. % values and more details on
the used amounts.

Joshua Boniface fe73dfbdc9 Use current live value for bridge_mtu
This will ensure that upgrading without the bridge_mtu config key set
will keep things as they are.

Joshua Boniface 8f906c1f81 Use power off in fence instead of reset
Use a power off (and then make the power on a requirement) during a node
fence. Removes some potential ambiguity in the power state, since we
will know for certain if it is off.

Joshua Boniface 50d8aa0586 Add handlers for client network MTUs
Refactors some of the code in VXNetworkInterface to handle MTUs in a
more streamlined fashion. Also fixes a bug whereby bridge client
networks were being explicitly given the cluster dev MTU which might not
be correct. Now adds support for this option explicitly in the configs,
and defaults to 1500 for safety (the standard Ethernet MTU).

Addresses #144

Joshua Boniface f6f6f07488 Add timeouts to queue gets and adjust
Ensure that all keepalive timeouts are set (prevent the queue.get()
actions from blocking forever) and set the thread timeouts to line up as
well. Everything here is thus limited to keepalive_interval seconds
(default 5s) to keep it uniform.

Joshua Boniface 3b805cdc34 Fix failure to connect to libvirt in keepalive
This should be caught and abort the thread rather than failing and
holding up keepalives.

Joshua Boniface 06f0f7ed91 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 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.
