Readthedocs failed to render Drydock exceptions with error:
> WARNING: autodoc: failed to import exception xxx from module
> 'drydock_provisioner'; the following exception was raised: No module
> named 'drydock_provisioner'
Trying to add Drydock requirements to the installed requirements list,
so that Readthedocs has all modules, including those needed for the
Drydock itself.
Unify docs building by utilizing Zuul docs-on-readthedocs template job.
Cosmetic readability changes:
1. combined all Makefile .PHONY targets into one
2. merged multiple LABEL instructions in Dockerfile into one

This patch set changes Drydock's exceptions documentation
(contained underneath operators guide) because it isn't rendering
correctly as a list table on RTD (the autoexception information
is missing) [0].
The easy fix is to change the tabularized view (list table)
into basically a series of autoexception classes which sufficiently
captures the level of detail required, anyway.
Note that running `tox -e docs` locally and opening the resulting
index.html page appears to work -- but not when hosted on RTD.
