BOSH deployment
We upgraded from 7.8.3 -> 7.9.1
We use integrated authentication for admin and cf authentication for developers, and one team uses github auth.

web nodes were in error after upgrade completed.
Failed with:
error: server: Failed to open connector cf: failed to open connector: unknown connector type "cf"

Pertinent config:

      cf_auth:
        api_url: https://<redacted>
        ca_cert: |
        <redacted>
        certificate: |
        <redacted>
        client_id: concourse-platform-1.<redacted>
        client_secret: <redacted>
        skip_ssl_validation: true       
      displayer_user_id_per_connector:
      - cf:email
      - github:username

Reverting to 7.8.3 versions restored web node functionality.
