Review request for Ambari, Mahadev Konar and Sumit Mohanty.


Bugs: AMBARI-4621
    https://issues.apache.org/jira/browse/AMBARI-4621


Repository: ambari


Description
-------

*Steps to reproduce:*
# Start 10 node cluster.
# On Step-9 of installer wizard while ongoing install command, Stopped ambari-agent on 9 hosts.
# Hit Retry button.
# Some of the host_components ended up in INSTALL_FAILED state, some in UNKNOWN state and
others in INSTALLING state. Host components in INSTALLING state never transitioned to any
other state.

*Reason*:
The _ActionScehduler.doWork()_ depends on the HostRoles to timeout before aborting the operation
in order to update Host Component status.
This particular issue is caused by a the timing of the change in Host state to UNKNOWN, which
happens after processing of in progress stages and before Abort.
