Add noqa everywhere that it is easy to do so

Hacking attempts to standardize the style guide for OpenStack, but
ultimately it is up to each project to accept and enforce each rule.
Going with that, give each project finer grained control over enforcing
each rule and support noqa where possible. This is a change of policy
from only supporting noqa where a clear example was given needing it.

This patch adds noqa support to every check that is easy to do so on.
This attempts to preemptively support noqa, without going out of the
way, as physical line checks don't automatically understand noqa like
logical_line checks.

Add noqa too:
H701
H702
H232
H234
H235
H237
