Dynamic roles

[fridim]

This change, if applied, adds hooks in all stages to dynamically load ansible roles on differents hosts.

• always localhost for pre-infra, infra, destroy
• groups of hosts for post-infra, pre-software, software and post-software steps

ex:

agnosticd_pre_infra_roles:
- name: infra-ec2-ssh-key
- name: infra-aws-capacity-reservation
  when: a custom condition

agnosticd_pre_software_roles:
- name: set-repositories
  group: all
- name: install_common
  group: all
- name: bastion-lite
  group: bastions
- name: bastion-student-user
  group: bastions
- name: host_virtualenv
  group: bastions

Can be used coupled with agnosticd_dynamic role:

agnosticd_dynamic_role_galaxy_sources:
  - name: docker
    src: geerlingguy.docker
    version: 0.2.0

agnosticd_post_software_roles:
- name: docker
  group: bastion
