John H. Tran 480052fc16 added mongodb auth
Implements bug 1022679.  mongodb needs auth=true to be turned on, and user
accounts in the appropriate dbs would need to be created.  Add to ceilometer
conf:

'database_connection=mongodb://username:password@<hostname>:<port#>/<dbname>'

"""Tests for ceilometer/storage/impl_mongodb.py
.. note::
(dhellmann) These tests have some dependencies which cannot be
installed in the CI environment right now.
Ming is necessary to provide the Mongo-in-memory implementation for
of MongoDB. The original source for Ming is at
http://sourceforge.net/project/merciless but there does not seem to
be a way to point to a "zipball" of the latest HEAD there, and we
need features present only in that version. I forked the project to
github to make it easier to install, and put the URL into the
test-requires file. Then I ended up making some changes to it so it
would be compatible with PyMongo's API.
https://github.com/dreamhost/Ming/zipball/master#egg=Ming
In order to run the tests that use map-reduce with MIM, some
additional system-level packages are required::
apt-get install nspr-config
apt-get install libnspr4-dev
apt-get install pkg-config
pip install python-spidermonkey
To run the tests *without* mim, set the environment variable
CEILOMETER_TEST_LIVE=1 before running tox.
