OAuth UI flow

[galvana]

Closes #3620

Description Of Changes

Added UI support for the OAuth2 authorization code flow. We already had all the API endpoints for this workflow but we needed to be able to trigger them from the UI.

Code Changes

• Updated the connector parameters form to show an Authorize integration button than needs to be clicked before Test integration becomes available.
• Added a referer field to the authenticationrequest table to be able to redirect the user back to the system page in Fides after the integration is authorized.
• Added a authorization_required flag to each connection type
• Added an authorized flag to connectionconfig

Pre-requisites

Follow the setup found here

Steps to Confirm

• Create a integration with a connector using the oauth2_authorization_code authentication strategy
• Click on Authorize integration
• Fill out the 3rd-party's login form
• Verify you are automatically redirected to the integration tab for your system in Fides

BE looks good to me @galvana! relatively straightforward updates, it's nice how cleanly the support has slotted in. can't comment much on the FE code though 😄

i also didn't get a chance to test manually but the video you posted looks 💥 ...that really turns up oauth integrations to the next level!
