Fix bugs and update WebServiceMockRequesting

1. Rename method WebService.performRequest with base requests to WebService.performBaseRequest. Bug: use requests as WebServiceBaseRequesting, but require WebServiceRequesting with response type.
2. Fix bug: after finished request it don't removed from list requests in process in WebService.
3. In WebServiceMockRequesting return type now generic ResultType in method responseHandler().
4. In WebServiceMockRequesting.createHelper() method removed identifier parameter.
5. All WebService.cancelRequest and WebServiceRequestProvider.cancelRequest renamed to cancelRequests.
6. Add cancelRequests for Request type (ignore requestKey).
7. Change logic WebServiceRequestProvider.cancelAllRequests - now cancel only current requests type.

Result Types in Requests, Thread safe, Mock Engine and Providers.

1. WebServiceRequesting.requestKey as optional. If Request as Equatable or Hashable, requestKey = request, else nil.
2. WebServiceRequesting now is generic protocol and require Result Type.
3. WebServiceResponse now is generic and can convert response to concrete type. Closures in WebService now use WebServiceRequesting.ResultType as information for response type.
4. WebService class now full thread safe.
5. Added WebServiceMockEngine for emulator data from server.
6. Support Custom and Request Providers.
