Runtime config should be put in config/runtime.exs?

Hi all,

currently the guide shows that we configure the runtime environment like this: https://github.com/ueberauth/ueberauth_google/blob/master/README.md#installation

Use that if you want to read client ID/secret from the environment variables in the run time:

config :ueberauth, Ueberauth.Strategy.Google.OAuth,
client_id: {System, :get_env, ["GOOGLE_CLIENT_ID"]},
client_secret: {System, :get_env, ["GOOGLE_CLIENT_SECRET"]}

Should we put the config in config/runtime.exs like the following:

config :ueberauth, Ueberauth.Strategy.Google.OAuth,
client_id: System.get_env("GOOGLE_CLIENT_ID"),
client_secret: System.get_env("GOOGLE_CLIENT_SECRET")
