Bug#1192017-Added user quota info for Compute.

Added procedures for managing user quota info in Compute.
Updated the procedure for setting default quotas (to match the
manpage;'default' moved to end of command). Updated displayed tables,
and updated the listing of quota name/descriptions to match. Also
updated the title of the networking quotas page to be consistent with
other sections.
Updated dashboard page: added note about tenant user updates, combined
compute and block storage tables, removed floating and fixed ip descriptions
(were removed from dashboard listing), fixed procedures to match
Havana 3 changes.
