add lower-constraints job

Create a tox environment for running the unit tests against the lower
bounds of the dependencies.

Create a lower-constraints.txt to be used to enforce the lower bounds
in those tests.

Add openstack-tox-lower-constraints job to the zuul configuration.

See http://lists.openstack.org/pipermail/openstack-dev/2018-March/128352.html
for more details.

monasca-ui specific changes:
- Unlike other projects, monasca-ui does not support python3 unit tests yet.
  python2.7 is used as basepython. This should be updated to python3 later.
- Bump the the minimum version of python-monascaclient to 1.8.0
  to pass test_client unit tests.
- nose-exclude needs to bumped to 0.5.0 to run all existing unit tests.

lower-constraints.txt is modified to match the latest horizon requirements
https://review.openstack.org/#/c/555491/:
- unit tests fails with Django 1.8. It passes with Django 1.11.
  Horizon Rocky bumped the Django min version to >=1.11, so it makes sense
  to bump the Django min version to 1.11.
- django-babel needs to bumped to 0.6.2 to support Django 1.11 and 2.0.

https://review.openstack.org/555402 allows us to bump lower requirements.
