OpenID 'id_token_signing_alg_values_supported' should be honored

[Former user]

Current implementation doesn't honor 'id_token_signing_alg_values_supported' in /.well-known/openid-configuration.

Currently, we have to hardcode the algorithm in source code to support any algorithms that's is not 'RS256'. However, the code would be broken if we change the signature algorithm from the hardcoded one.

proposal: to honor OpenID: 'id_token_signing_alg_values_supported'. The supported algorithms will be pulled from /.well-know/openid-configuration.
