Deprecate connection config fields in UI

[TheAndrewJackson]

Closes fidesplus#947

Description Of Changes

This PR makes the ConnectionConfig.name field optional and removes both the ConnectionConfig.name and ConnectionConfig.description fields from the integration tab form.

Code Changes

• Add migration that makes ConnectionConfig.name optional
• Remove name and description fields from the integration form
• Stop defaulting ConnectionConfig.key to ConnectionConfig.name for saas connectors if it's left empty. This is because the name isn't guaranteed to be there anymore. Now it defaults to the instance key.

Steps to Confirm

• Run fides and the admin ui
• Create and edit a database connector
• Create and edit a saas connector

Pre-Merge Checklist

• All CI Pipelines Succeeded
• Documentation:
  • documentation complete, PR opened in fidesdocs
  • documentation issue created in fidesdocs
• Issue Requirements are Met
• Relevant Follow-Up Issues Created
• Update CHANGELOG.md
• For API changes, the Postman collection has been updated
