Code Issues Proposed changes

Allow horizon to function without nova

Browse Source 
Adds conditional block to nova quotas to exclude them if nova is not
enabled; adds 'permission' checks to the project overview and
access_and_security panels to only enable them if compute is enabled;
adds permission checks on compute and image to the admin overview
and metadef panels; disables 'modify quota' and 'view usage' project
actions; disables 'update defaults' if there are no quotas available.

The 'access and security' panel still appears (under Compute) but
tabs other than the keystone endpoint and RC download tab are hidden.
