Use cached branch list in dynamic config
When performing a dynamic reconfiguration, we currently ask
sources for a list of all branches on all projects. This takes
about 2.5 minutes at openstack production scale. Instead, since
there should not be any changes to branches introduced by a
dynamic reconfiguration, use the previously cached list of branches.
The dictionary referenced here has an entry for every project branch
regardless of whether there is any configuration in that branch, so
it is an effective cache of all branches.
