update requirements by pip-tools

We have script for updating our requirements. But we can move to some better:

```
pip-compile development.in
pip-compile documentation.in
pip-compile production.in
```
i think this looks much better.

- [ ] remove `check-requirements.py`
- [ ] add pip-compile for `upgrade` command into makefile
- [ ] describe into the documentation how use *.in files for that
