* Unify ansible-galaxy install -r
* Minor nit fixes for docs
* Re-align warnings
* Fix up integration test
* Fix up test where no roles/collections were in file
Use "name" when possible rather than "src" to make the examples
of roles and collections in a single requirements files more
coherenant. Fundamentally, roles and collections are completely different.
But we can make the requiremets file easier to read by unifying the
format as much as possible.
