(REST) As an admin, I would like to review plan(s) triggering

Excessive requests against repository server can be made (unnecessarily) due to misconfiguration on Plan Configuration >> Triggers tab, preventing builds from being triggered and/or source code checkout from fetching/pulling repository changes.

As an administrator, I would like to review plans that are set up with Repository Polling - Periodically, displaying information about:

• plan
• repository set up in trigger
• its interval

The same information should become available for Repository Polling - Scheduled and Scheduled
