AWS LB should return configuration metadata without HTTP redirects

[yurem]

Right now AWS LB has next rule https://gluu.testingluuk8.org/.well-known/openid-configuration --> https://gluu.testingluuk8.org/oxauth/.well-known/openid-configuration which led to HTTP code 301 Moved Permanently.

As result client make second request to load required resource. This slow down configuration load.

CE handles this without redirect:

#180

We need to try to find out how to avoid redirect. After that we can revert commit: 8927ae84a6d2bba8b0239f0990b9658c681572cb
