MapR plugin now supports event logs. To complete this task several additional changes were made: 1. Move node awareness checking from within configure_topology method 2. Add instances parameter to set_cluster_mode 3. Move topology map generation to cluster context 4. Move configs resolving to cluster context Change-Id: Ic00b27f57eacf5664980358b7fd154632ef3f31e Implements: blueprint mapr-event-log
