[RFE] Earlykdump should poweroff the system after capturing the kernel crash dump of the booting kernel.

Issue

• By default, earlykdump reboots the system after capturing the kernel crash dump (vmcore) of the booting kernel. If the problematic system is continuously crashing due to some issue during the early boot stage then earlykdump can create the following problems:
  • It can make the system unstable by rebooting it in the loop.
  • It can capture multiple copies of the kernel crash dump (vmcore) that can fill the entire disk space of the dump target.
