Fix: Contributor component does not function with the setVisibility f…

…unction (#1145)

* Added custom validation handler interface. Fields that implement this interface will manage setting and unsetting validators themselves.
Added to setVisibility of field-base so that validation can be reapplied correctly for this type of field after visibility is re-enabled.

* Fixed interface name

* Fixed syntax error

* Updated docker deploy script to support forward slashes in the branch name
