Backend - generate ID verification code

[adriaaaa]

Description

When Fides admins are using our ID verification solution, Fides will need logic to validate that a submitted verification code matches (or doesn't match) what it is expecting to receive. Fides should create a privacy request if the codes match. Fides should not create a privacy request if the codes do not match.

Assumptions

• this includes figuring out how to store the code temporarily
• scope of this ticket includes sending out the code to the subject

Acceptance Criteria

1. Show that Fides will not accept a privacy request if the ID verification code provided does not match the one sent to the user
2. Show that Fides will accept a privacy request if the ID verification code provided matchs the one sent to the user

I'm going to split work a little differently:

#1062 - separate endpoint that verifies and then queues the privacy request
#1010 - generate code and send to the user when they attempt to create a privacy request and they have identity verification turned on.

Note to self: Add documentation as part of this work

Flow:

• check if subject identity verification is on
• if so, create the privacy request/cache the identities, and set the status of the privacy request to "identity_unverified".
• generate a verification code and email that to the user.
• continue, don't queue the privacy request.
