Description

In ActivitiesManager, if there's no yarn configuration in mock RMContext, cleanup interval can't be initialized to 5 seconds by default, causing the cleanup thread keeps running repeatedly without interval which may bring problems to mockito framework, it caused OOM in this case, internally many throwable objects were generated by incomplete mock.
Add configuration for mock RMContext to fix failures in TestLeafQueue.
