Pulp

This is a commonly reported issue by users.

If a user specifies both the version and upgrade vars for a plugin under pulp_install_plugins, pulp_installer fails.

(This might be only when the upgrade var is set to true).

This is because even though a command like pip install --upgrade pulp-file=0.3.0 is valid, the ansible pip module refuses to let you specify version and state=latest (state=latest maps to pip --upgrade, and to our upgrade: true).

I was hoping that specifying both would upgrade all dependencies.

We should probably address this omitting or specifying false for upgrade, whenever version is set.

Make sure to update the pulp role's README.md for this.
