Add action for authorized keys

Description

We need an action to manage authorized keys for specified users

Proposal

ssh_authorized_keys:
  - user: "bdaca"
    keys:
      - "key1"
  - user: "tziol"
    keys:
      - "key2"
      - "key3"

• Action creates .ssh directory and populates authorized_keys file (if necessary) with provided keys for each provided user.
• Action does not modify any unspecified users.
• Action removes all other keys, that are not on the user's list.
