Please support --fail-if-no-pacts-found in verifier configuration

Agree, useful feature. It is hard to make Providers run contract test in new environment when no consumers exist yet

Support was added in pact-js in 2022: https://github.com/pact-foundation/pact-js/issues/941

            var forVerificationUri = new Uri(pactBrokerUri + $"/providers/{providerName}/for-verification");
            var response = await _httpClient.PostAsync(pactBrokerUri, data);
            var result = await response.Content.ReadAsStringAsync();

            // return true if at least one pact is returned
            return result.Contains(providerName);
        }
