Migrate Cognito in tools space

[MCatherine1994]

Describe the task
Migrate Cognito to LZA in tools space with the following:

• User Pool
• IDPs
• FAM and FOM Cognito App Clients

This ticket only deals with Cognito setup, no user in User Pool yet.

Acceptance Criteria

• Add User Pool terraform file to our new terraform folder, and run the pipeline to set it up in LZA Cognito
• Add IDP terraform files to our new terraform folder, and run the pipeline to set it up in LZA Cognito
• Add application client terraform files to our new terraform folder, and run the pipeline to set it up in LZA Cognito (FAM and FOM)

Additional context

• It is not possible to keep the same application id (App Client's Client ID - used for downstream app, including FAM). Heartwood team will need a strategy when ready for downstream apps to port over their app to LZA.
• Initial thought that we don't need to migrate users from user pool (as long as the user's guid from IDP in Cognito is the same), but to be confirmed.
• We probably can't do much after this ticket is done, when we get more resources up (db, apis, WAF, auth-lambda) to LZA we can do testing primary from pointing FAM/FOM login to new LZA Cognito.

Please note, we also need to add the new Cognito domain url to Pathfinder's SSO integration:
