Pulp

Install Pulp with ansible-pulp allows specifying which plugins to install with the `pulp_install_plugins` variable, e.g.:

pulp_install_plugins:
  pulp-file: {}
  pulp-docker: {}

Unfortunately, this leads to the following error:

It appears that pulp-docker tries to install rc6 version.

Further, this means that errors such as in the following issues can occur:
https://pulp.plan.io/issues/5626
https://pulp.plan.io/issues/5624

Consistent dependencies should be available when installing via anisble-pulp.
