exclusive + pubkey list results in only last key being added

[abeluck]

When you specify a list of pubkeys for a single user:

      - username: admin
        exclusive: true
        pubkey:
          - "ssh-rsa ..."
          - "ssh-dsa ..."

only the final key is kept, the others are discarded.

As per the authorized_key docs

Multiple keys can be specified in a single key string value by separating them by newlines.
This option is not loop aware, so if you use with_ , it will be exclusive per iteration of the loop.
If you want multiple keys in the file you need to pass them all to key in a single batch as mentioned above.
