[New feature] Enforce SSL on SPS endpoints

[LucaCinquini]

Clients have been complaining that the Airflow installation is still accessible via HTTP. We need to enforce SSL on the Airflow and OGC endpoints.

[LucaCinquini]

Brad has created a PR, which Luca has tested to successfully reach endpoints on his personal installation.
Next steps:
o Make sure integration tests still work (might need to trust the SSL certs).
o Remove Cognito login on top-level proxy or on Airflow.

For now, Brad has successfully re-enabled the SSO certificates on the SPS and Airflow load balancer that are reachable only within the JPL network. The SSL certs are invalid because they refer to "*.dev.mdps.mcp.nasa.gov" but these endpoints will only be used by developers, who can dismiss the warnings in the browser.
DAGs to these personal installations will have to be published via the ./post_deployment.sh script which uses CURL and ignores the SSL problems.
