[PATCH v3 09/13] introduce the auto_reset_crashkernel option to kdump.conf

This option will determine whether to reset kernel crashkernel to new default value or not when kexec-tools updates the default crashkernel value and existing kernels using the old default kernel crashkernel value. Default to yes.
