Adding --check-disk flag and unity error exit code

[rounak-adhikary]

1. Adding a new flag --check-disk to be used to check (only on iDRAC 9) if the disk supports secure erase without actually trying to erase it.
2. Adding exit code as 1 in cases where there is a failure so that this script can be used in simple automations.
