Refactor requesting data from API with new useApiRequest custom hook

[iburakov]

Now API requests for data are done with useEffect hook and useState vars. It can be generalized with new useApiRequest custom hook implemented for this purpose for all components where data is requested with server API.

Example of refactoring: 7b607d1. See useApiRequest usage for more.

Further parametrization of the hook (including useApiRequest.tsx modification) may be required.
