roles/git: ssh known_hosts is now idempotent

- roles/git now uses blockinfile to ensure the github ssh keypairs are trusted, and to allow subsequent ssh keypairs to be trusted and not overwritten by future runs.
- this commit marks idempotency for all roles. after a successful run of this playbook, subsequent runs will result in a change=0 !!!!!
