ARA_CSRF_TRUSTED_ORIGINS is broken

[R. P. Taylor]

What is the issue ?

It is documented here: https://ara.readthedocs.io/en/latest/api-configuration.html#ara-csrf-trusted-origins
But it does not work. Running ara with this env var

        - env:
          - name: ARA_CSRF_TRUSTED_ORIGINS
            value: https://ara.example.org

results in pod failure and crashloopbackoff with these logs:

What should be happening ?

Ara should run with the setting applied correctly. Related to #345

We can't access the admin dashboard anymore due to this error, nor can we run an older version before the CSRF implementation. It doesn't look like there is a way to disable CSRF either ... ?

Oops the var is supposed to be a list, not a string, nevermind. To do that with an env var in k8s the syntax has to be like this:

      - env:
        - name: ARA_CSRF_TRUSTED_ORIGINS
          value: '[''https://ara.example.org'']'

or

      - env:
        - name: ARA_CSRF_TRUSTED_ORIGINS
          value: "[''https://ara.example.org']"

Hi @rptaylor, that was tricky but I'm happy you figured it out and thanks for coming back with the fix so we don't have this:
