[CRV-302] Created new REST method for listing choreographies and adapted methods  to store methods and choreography diagram

[CRV-299] Now choreography create function receives synthesis processor key and instanciates relationship

[CRV-291] Provided EE selection from console and adapted REST interface for create and enact methods

Added check in console if ee details for a choreography are available and updated password input field

[CRV-278] Now ChoreographyService's create() and update() modify only the internal storage; a new enact() method is provide to actually involve the configured EE instance
