OpenPOWER: Clear system and resource dump entries while powering off
The dumps like system and resource dumps are stored in host memory
and that will be lost during a power off, so the entries in BMC
dump-manager for those dumps will be stale after a power off.
This commit adds a service to call deleteAll to clear the entries
for system and resource dumps during system power off.
Tests:
1 - Created a resource dump and system dump
and activated the service
Result: Both dump entries are cleared
2 - Created a resource dump and system dump
powered off the system
Result: Both dump entries are cleared
