This does a few things:
* Update hacking to the version in global-requirements. Old hacking was
installing a version of pbr that was breaking other packages.
* Fix all the hacking/pep8 rules that updating hacking raised.
* Do some general docstring cleanup, while already in there cleaning up
a bunch of docstrings due to H405 violations.

Closes-Bug: #1461717
The docstrings here were all giving WARNINGs or ERRORs during the docs
build, and were generally making unappealing looking developer
documentation. I corrected the syntax and did what was neccessary to
make the build come out clean.

(cherry picked from commit c0921cdff372ce1fd6df1c4ab4eb5463e2cba0e4)
Using DynamicLoopingCall involved a few hacks to make it work properly. This
new BackOffLoopingCall will start an exponential backoff (with a configurable
jitter) when there is a failure. The backoff will continue until the given
function returns True or timeout is about to be exceeded. The function will
run indefinitely until either an exception is raised or timeout is reached.
I plan to merge this into oslo loopingcall and switch the heartbeat to this.
