Key - Manage repository keys

⚠️ Be aware: This is not yet implemented!

The key command allows you to set multiple access keys or passwords per repository. In fact, you can use the list, add, remove, and passwd (changes a password) sub-commands to manage these keys very precisely:

    $ rustic key list
    enter password for repository:
     ID          User        Host        Created
    ----------------------------------------------------------------------
    *eb78040b    username    kasimir   2015-08-12 13:29:57

    $ rustic key add
    enter password for repository:
    enter password for new key:
    enter password again:
    saved new key as <Key of username@kasimir, created on 2015-08-12 13:35:05.316831933 +0200 CEST>

    $ rustic key list
    enter password for repository:
     ID          User        Host        Created
    ----------------------------------------------------------------------
     5c657874    username    kasimir   2015-08-12 13:35:05
    *eb78040b    username    kasimir   2015-08-12 13:29:57
