This commit updates all files that weren't passing yamllint for them to
pass.
A new yamllint target has been added. One can run `tox -e yamllint` or
`yamllint -s .` locally to ensure yaml files are still passing.
This check will be enabled in the CI so it can get on every new
contributions, and prevent merging non-compliant code.

`oc new-app --template=postgresql-persistent` has been kind of a pain. It would attempt to create a Persistent Volume, but does not allow you to specify the storageClass.
This code assumes that a Persistent Volume is already available and will fail with a helpful error message if it is not.
