Add a trigger to a plan. Pre-defined types are: polling, remote, remoteBitbucketServer, scheduled. One or more repositories can be specified for pre-defined type triggers based on repositories or custom types. Polling triggers default to all plan repositories or use repository @all. Custom types can be specified with the appropriate trigger key (or alias) and all required parameters using the various field parameters. Use of the name parameter is deprecated - description should be used instead.
