Small edits on help strings

These were initially noted during import into the manuals at
https://review.openstack.org/67502

Fixes include rework of text, missing or extra spaces, wrong
capitalization and no sentence style capitalization.

A hacking check has been added that tests that all config options
start with a capital letter.
