Recreating the gafaelfawr token

If Gafaelfawr has restarted and its redis service’s storage has been lost, services that rely on having a token from gafaelfawr to allow them access to other services will no longer be able to authenticate.

This is seen in the nublado2 namespace; when it happens the gafaelfawr-token no longer allows access to Moneypenny and user pod spawning fails.

To correct the issue:

1. Force a restart of the gafaelfawr-tokens deployment in the gafaelfawr namespace. This will recreate the secret in nublado2.
2. Force a restart of the hub deployment in nublado2. This will restart the hub with the new, correct token.
