When doing a post api call to notify of status of build, the "parent" value is not included in the body, which means that the "Required Build" functionality does not work in Bitbucket.

Fix would be to add "parent" to the buildStatus object in the plugin, which should be the path to the job as in the Atlassian supported Bitbucket server integration plugin.
