Revert "Remove the update default quotas feature"

This reverts commit ed586a0355fb99a5b1fbeadfc0625f0ceffe8b72.

The quota_class subcommand in python-novaclient was used to set default
quota values so it shouldn't have been removed. As now it is being
restored, the defaults quota panel is being restored too.

Resolved merge conflicts by hand in:
openstack_dashboard/api/cinder.py
openstack_dashboard/dashboards/admin/info/tabs.py
openstack_dashboard/dashboards/admin/info/tests.py

Updated translatable segments to match refactors in
openstack_dashboard/dashboards/admin/defaults/workflows.py
openstack_dashboard/dashboards/admin/defaults/tables.py

Fixed most egregious post-merge styling errors in
openstack_dashboard/dashboards/admin/defaults/templates/defaults/index.html
(probably should have been separate, but I just couldn't let it out that way!)

Removed unrelated file that was allowed to be part of the original commit
doc/source/topics/settings.rst

Partial-Bug: #1299517
Unbundle bootstrap and use xstatic version

This uses the xstatic-packaged versions of bootstrap and bootstrap-datepicker.
It requires newer versions of pyscss and django-pyscss, as there were some
bugs in there that were just fixed upstream.
