Docs: Elaborate on feature flag in HACKING file

This is to elaborate on feature flag functionality in Tempest's
HACKING.rst. Currently, there isn't much documentation on feature
flags in Tempest or how to add them. The only place feature
flag is mentioned is in this file. Since testtools.skip(Unless|If)
is a common way of using a feature flag, it is mentioned. Also,
Tempest's interaction with DevStack is an important thing to mention
when explaining how to introduce a new feature flag.
