CDPD-17194: Upgrade to Ember.js 2.2.1+ due to CVE-2015-7565
Prior to this upgrade, YARN was pulling in ember.js 2.2.0 which is vulnerable to CVE-2015-7565. This CVE can be avoid by upgrading to ember.js 2.2.1.
COMPX-5240: Restarting parent queue does not restart child queues in weight mode
When a dynamic auto child creation enabled parent queue is stopped in weight mode, its static and dynamically created child queues are also stopped. However, when the dynamic auto child creation enabled parent queue is restarted, its child queues remain stopped. In addition, the dynamically created child queues cannot be restarted manually through the YARN Queue Manager UI either.
