Enable relaxed matching of enabled and access properties

The lowercase form of the endpoint ID needs to be used so that
relaxed matching of properties, as provided by
ConfigurationPropertySources, works as intended. Without this
change the id of the endpoint in a property had to be an exact
match of the endpoint's ID.

Closes gh-43302
