fence-gece earlyexit disussion

[ab-mohamed]

Hi,

I have created this issue to host the technical discussion between SUSE HA engineering and Google SAP teams about
1e1aed1

Google added the 'earlyexit' logic to the power cycle function in the fence-gce fencing agent. This gives the option to proceed once the reset API call succeeds but not wait till the actual reboot operation finishes; this can result in a faster failover. Several customers requested this function extension, and Google already made the development efforts.

They want to revert it in #545
