Cleaned up the code a bit, also checks TOTP before attemping to verify
user.
This addresses the potential for an attacker to try at a password
and/or confirm that the password is correct unless they have a valid
TOTP code for the request. A failed TOTP response will trigger a
throttle count on the login as well.
Adds memory/disk/etc. fields as well as selecting the service type and
option. Still need to add in the ability to set the variables once an
option is selected.
