Fix instack-undercloud PEP8 failures and requirements constraints

PEP8 have new changes that make invalid escapes a hard failure.
Also, it's failing on the requirements check.

Also the build-openstack-releasenotes job taker the setup info
from master, as we do not have master anymore we can not run the
build-openstack-releasenotes job.

This submission fixes:
- Unit tests failing with scaping incorrectly backslashes.
- Lower constraints.
- Requirements.
- Test requirements.
