add patch for 1.8.1 compatibility. 1.8.1 couchbase does not have the CouchAPIBase node attribute, therefore len(capiEpList) will always be zero. This results in IsValid() returning false when config.bktType == BktTypeCouchbase. Instead, we should not check the length of capiEpList as part of the validation of the routeconfig.
