REST API verison

Using the plugin version 2.x, the REST-API-VERSION in the URL will be the major version of the REST API, which is currently 1.

Using the plugin version 1.x, the REST-API-VERSION in the URL will be the same as the plugin version until version 1.2.1 (including).

 

After version 1.2.1 the REST-API-VERSION will remain 1.2.1. This decision was inspired by https://github.com/everit-org/jira-worklog-query-plugin/issues/17 and we do not want to bother the users with MINOR and PATCH version changes in further 1.x releases.
