Enable CORS for https://otp.gophillygo.org/

[flibbertigibbet]

Setting the otp_host ansible environment variable to https://otp.gophillygo.org/ fails because CORS is not configured for that domain. However, setting the OTP host to the Cloudfront domain that https://otp.gophillygo.org/ points to does work.

Configure https://otp.gophillygo.org/ to allow CORS on AWS. This will allow for local development while pointing to the production OTP server, without needing to update the otp_host after each redeploy.

Is this related to Access-Control-Allow-Origin is set to https://gophillygo.org? Having some difficulty understanding the failure and success behavior you're describing.

[flibbertigibbet]

The failure that routing requests to OTP fail if the otp subdomain is used for otp_host in the group_vars.

(This is pretty low priority, by the way, since the Cloudfront URLs work fine.)
