Add new build option to generate ansible roles out of profile ansible playbooks

[ggbecker]

Description:

• Add new build option to generate ansible roles out of profile ansible playbooks

Rationale:

• This is a first step towards Ansible Collection generation and publishing
• ~Installing these files is intentionally left out of the implementation. We are not interested in those single unit files.~
  • We need to install the files so they can be packed downstream as well.

Review Hints:

• Set the variable SSG_ANSIBLE_ROLES_ENABLED to true and build the content. Inspect the folder build/roles.
