Since the custom password is used to set the GPG admin
password as well as the TPM and GPG user passwords, an
8-character minimum is required. Inform the user of this,
and validate custom password length upon entry.

Normally we resort to default passwords for OEM reset, however we have a
use case where it would be convenient to set a custom password instead.
This patch adds a simple prompt (that defaults to the defaults if you
hit Enter) that enables someone using the OEM reset to enter a single
password that will replace the defaults (TPM, GPG Admin, GPG User).
Add oem-factory-reset script which performs an unattended
reset and configuration of the device's TPM, GPG security token,
and boot device / boot selection.
