      Description

      Polish uber-AM (MAPREDUCE-2405). Specifically:

      • uber-specific counters ("command-line UI")
      • GUI indicators
        • RM all-containers level
        • multi-job app level [if exists]
        • single-job level
      • fix uber-decision ("is this a small job?"):
        • memory criterion
        • input-bytes criterion
      • disable speculation
      • isUber() method (somewhere) for unit tests to use
      • delete (most of) old UberTask code (MAPREDUCE-1220; came in with initial MR-279 branch)
      • implement non-RPC, local version of umbilical
      • AM restart (default 4 tries) on another node on any task-attempt failure
      • uber-specific metrics?
      • rename configurables? (still "ubertask"-based)
