OPS-1593 As an operator, I want sudo_user converted to become user in roles and plays, for compatibility with Ansible 2.x

There are still a lot of warnings that need to be fixed but these
were the only failures.

If a git version is specified as a branch, and the commit referred to is
already on the local working tree, but the branch is not, then the
checkout will fail.

This is because the Ansible 1.9.3 module would check to see if the
commit was already present, and if so, did not fetch. This meant the
branch wasn't defined in the local working tree.

This can happen if you make a branch but there aren't any changes on the
branch.

Using latest versions of rbenv, bundler, rake, and rubygems.

In order to support --check we need to ensure that registered
vars exist before checking their stdout. Otherwise ansible
errors out.

These are some minimal changes to support 1.3, does not yet include role
dependencies.

In certain states, ruby is installed but the env is not setup so it is importart
to always run the environment update task and the rehash task.

The rbenv install task prompts if the version of ruby is already installed. This
freezes the build so skip it if the version directory already exists.
