Description

Steps to reproduce:

1. Start 10 node cluster.
2. On Step-9 of installer wizard while ongoing install command, Stopped ambari-agent on 9 hosts.
3. Hit Retry button.
4. 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.
