Recently the logic in xDS Name resolver was changed to support encoded authorities: #10207.
This seems to cause an issue for xdstp replacements which would percent encode the authority for the replacement causing double encoding.
For example:
URI = xds:///path/to/service
Authority = path%2Fto%2Fservice
xdstp resource = xdstp:///envoy.config.listener.v3.Listener/path%252Fto%252Fservice
Here the authority is encoded due to slashes and during replacement we percent encode it again causing %2F to change to %252F.
To avoid this issue, use the encoded authority only for the getServiceAuthority() API and for all other use cases retain the unencoded authority.
