ejabberd_ctl: Add support for list and tuple arguments

Tuple elements are separated with :
List elements are separated with ,

For example:
  ejabberdctl add_rosteritem user1 localhost testuser7 localhost NickUser77l gr1,gr2,gr3 both
  ejabberdctl create_room_with_opts room1 conference.localhost localhost public:false,persistent:true
  ejabberdctl subscribe_room_many user1@localhost:User1,admin@localhost:Admin room1@conference.localhost urn:xmpp:mucsub:nodes:messages,urn:xmpp:mucsub:nodes:affiliations

Affected commands:
- add_rosteritem
- create_room_with_opts
- oauth_issue_token
- send_direct_invitation
- set_vcard2_multi
- srg_create
- subscribe_room
- subscribe_room_many
