Affected functionality
Added a config item to the OIDC provider (jwt_issuer). This config specifies the issuer for the OIDC provider configuration request. Previously, only the request host could be the issuer. This change allows users to define a different JWT issuer with a path.
Description of change
Updating OIDC provider config with new field (jwt_issuer)
Added validation for new config
Updated logic in handler to use newly created config in OIDC configuration response if config is defined.
