Edison Su f497c7c031 Bug: HA takes a lot of time to migrate VMs (trigger HA) to another KVM
host if there are multiple storage pools in a cluster.

The issue is as follows:
1. When CloudStack detects that a host is not responding to ping
requests it'll send a fence command for this host to another host in the
cluster.
2. The agent takes a long time to respond to this check if the storage
is fenced. This is because the agent checks if the first host is writing
to its heartbeat file on all pools in the cluster. It is doing this in a
sequential manner on all storage pool.

Making a fix to get rid of sleep, wait during HA. The behavior is now
similar to Xenserver.
