docs: customer facing quota documentation (rackerlabs#601)

* Add customer facing quota documentation and updated mkdocs.yml to include the quota doc in the Cloud Onboarding section.
Trying to fix signing.
Signed-off-by: David Keirns <[email protected]>

* Clean up trailing whitespace in openstack-quota.md

* switched from two space characters to <BR> as linebreak to see if that would appease the github checks.

* Fix trailing whitespaces, remove volume show command as well as results image, as it isn't really required.
