Merge pull request #3920 from UmanShahzad/uman/unpin-jenkins-jdk7

Unpin Jenkins JDK 7 requirement.

CHANGELOG.md

+- Role: jenkins_master
+  - Update pinned use of JDK7 in Jenkins installs to default JDK version from role `oraclejdk`.
+
 - Role: notifier
   - Added `NOTIFIER_DATABASE_ENGINE`, `NOTIFIER_DATABASE_NAME`, `NOTIFIER_DATABASE_USER`, `NOTIFIER_DATABASE_PASSWORD`, `NOTIFIER_DATABASE_HOST`, and `NOTIFIER_DATABASE_PORT` to be able to configure the `notifier` service to use a database engine other than sqlite. Defaults to local sqlite.
   - Deprecated: `NOTIFIER_DB_DIR`: Please use `NOTIFIER_DATABASE_NAME` instead.
