Review request for Ambari and Dmitro Lisnichenko.


Bugs: AMBARI-17030
    https://issues.apache.org/jira/browse/AMBARI-17030


Repository: ambari


Description
-------

Add an agent capability to auto-restart when the memory threshold for the
agent process exceeds a limit. This should be a configurable property (e.g.
agent_memory_threshold) where any positive value, say in MB, is a limit at
which agent should get restarted.

The restart itself should be executed when there are no
EXECUTION/AUTO_EXECUTION commands in pipeline. So when the condition is
reached for agent auto restart, a flag should be set to restart when agent is
not doing any work.

A hard limit should also be set where the agent will be restarted even if
there are commands in pipeline.
