On collection install, install run-time dependencies from meta/main.yml for each included role.

After installing an Ansible Collection:

• traverse the roles directory, and for each role, install any dependencies enumerated in meta/main.yml.

Part 2 ("After installing a traditional Ansible role, Install any dependencies enumerated in meta/main.yml") is implemented via:
#156
#158
#157

Part 1 ("After installing an Ansible Collection, traverse the roles directory, and for each role, install any dependencies enumerated in meta/main.yml."). This bug list two parts, but going to consider part2 here as split out into #138

This is not implemented currently as of (~0.3.0, 5ea70d3).

I'm not sure if it doing a transverse down into all of the roles looking for deps is consistent with the idea that a collection is the installable unit.

• Dependencies specified in a roles meta/main.yml are going to be a dep that points to another role, not necessarily a collection. Granted, this is fuzzy for the case of traditional roles available in galaxy (where the role is also sort of a Collection).
• role meta/main.yml deps are runtime deps and not necessarily install time requirements.
  • a role inside of a collection could have a meta/main.yml dep on another role inside of the collection, which would not have a name that mazer could resolve but ansible-playbook could resolve it at runtime.
  • a role inside of a collection could have a dep on a role that is not known to mazer (a locally installed role, or a role provided outside of mazer/galaxy)
• All of the roles within a collection would need to share the same transitive requirements. ie, roles inside a collection could not have dependencies that conflict with each other since there would be no way to solve them all at the same time.

Removing part2 of original comment "After installing a traditional Ansible role: Install any dependencies enumerated in meta/main.yml" as it is split out into #138

WONTFIX in lieu of collection being the unit of installation and dependencies. Roles that need roles from other collections should update the containing collection dep.
