Provide both pythonic Django part and the static assets (angular
directives and styles) for the new panel.
DEPLOY NOTES:
To enable panel itself, copy
openstack_dashboard/local/local_settings.d/_9030_profiler_settings.py.example
file from the previous commit to
openstack_dashboard/local/local_settings.d/_9030_profiler_settings.py
and copy openstack_dashboard/contrib/developer/enabled/_9030_profiler.py
to openstack_dashboard/local/enabled/_9030_profiler.py
To support storing profiler data on server-side, MongoDB cluster needs
to be installed on Devstack host (default configuration), see
https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/#install-mongodb-community-edition
for instructions. Then, change net:bindIp: key to 0.0.0.0 inside
/etc/mongod.conf and invoke `sudo service mongod restart` for the
changes to have an effect.
