Add user role check to API key router, plus option to download submission data for a project

Is your feature request related to a problem? Please describe.

• Recently we added API keys.
• We don't need granular API keys per project, but instead can have this based on user permissions.
• We use the existing auth checks for a user to determine if the user has access to the project, but this time via an API key.
• The user needs to be able to download submission data via API for projects they have access to.

Describe the solution you'd like

• Update API login dependency to use check_access on roles for a given user.
  • Return response if they have access.
  • Provide error if they do not have access.
• Add integrations router endpoint to download submission for a project.
  • This should wrap existing crud logic to keep things DRY.
