Cleaning up a little technical debt by adding docstrings
for our public APIs.
Note: I plan to submit a patch per file as part of this bug work.
These patches won't depend on each other. The last patch of
the series will close the bug.
Partial-Bug: #1614594
Change-Id: Ic0fdc5c77abcbb77a7ca08e4e00302a22ae8e4f5
DeviceNotFoundError is used in dragonflow. In an effort to move away
from requiring neutron.common, DeviceNotFoundError should be in
neutron_lib.

Update neutron-lib callbacks with the latest from neutron
in preparation for updates to the callback notification interface.
The callback updates also require a few module level functions
in the db package.
A few additional unit tests are also added for coverage as is
python docstrings for the public API contained herein.

Here we add the context module from Neutron, although it is
currently marked as private because it will undergo changes
related to the ongoing enginefacade and Keystone V3 work.
We also add some of the roles management methods from
Neutron's policy module. These are required for the initial
DB patches that follow this one.
Partially implements: Blueprint neutron-lib
