Using the new --list-dependencies flag, one can query dependencies for a
given filter. For example:

./build.py --list-dependencies heat swift
{'base': [{'openstack-base': [{'heat-base': ['heat-engine',
                                             'heat-api-cfn',
                                             'heat-api']},
                              {'swift-base': ['swift-object',
                                              'swift-proxy-server',
                                              'swift-container',
                                              'swift-rsyncd',
                                              'swift-account']}]}]}

Also added --list-images to list all available images.

We got rid of the kolla-mesos repo:
http://git.openstack.org/cgit/openstack/kolla-mesos/tree/README.rst

So we don't need things in the main kolla tree
related to Mesos/Marathon

This commit adds a few #nosec tags for non-issues.  I've examined
the code and determined that these don't represent security issues
so we should add a #nosec tag that tells Bandit not to find these
issues in the future.

Since kolla-mesos has been retired, there is no need in the code
base to keep the zookeeper implementation.  As a result, just remove
it.  If we were to keep it we need virtualenvs for that part of the
code base which installs the python dependencies related to it
for from-binary installs.

This just simplifies the implementation tremendously and culls dead
code.
