Presently should the ATA erasure operation fails, IPA halts the
cleaning process and the node goes to CLEANFAIL state as a result.
This failure could be the result of a previous cleaning failure
that left drive security enabled, for which code has been added
in an attempt to address this case by attempting to unlock the
the drive.
In the event that an operator wishes to automatically fallback to
disk scrubbing operations, the capability has been added through
a driver_internal_info field "agent_continue_if_ata_erase_failed"
that can be set to True, however defaults to False keeping the
same behavior that IPA presently exhibits in the event of ATA
erase operations failing.
