Start running the doc8 RST linter in the pep8 job. This will catch obvious errors like line too long, etc. Tried to fix most of the errors (there were a lot!), but added some ignore directives so we can address some files later. Did have to move a couple of files around as a double include was causing some issues, but content is unchanged. Change-Id: I336a9ee7729045da095be22ea0f58ee596967174

Transient DB Failure Injection
Neutron has a service plugin to inject random delays and Deadlock exceptions into normal Neutron operations. The service plugin is called 'Loki' and is located under neutron.services.loki.loki_plugin.
To enable the plugin, just add 'loki' to the list of service_plugins in your neutron-server neutron.conf file.
The plugin will inject a Deadlock exception on database flushes with a 1/50 probability and a delay of 1 second with a 1/200 probability when SQLAlchemy objects are loaded into the persistent state from the DB. The goal is to ensure the code is tolerant of these transient delays/failures that will be experienced in busy production (and Galera) systems.
