Fixes
- Fixed kbqa_cq_ru on Python 3.8/3.9 ([1609](https://github.com/deeppavlov/DeepPavlov/pull/1609))

Documentation

Other changes
- Updated model files upload script ([1607](https://github.com/deeppavlov/DeepPavlov/pull/1607)).

Major Features and Improvements
- Added `-i`/`--install` CLI argument and `install` argument to `deeppavlov.build_model`, `deeppavlov.evaluate_model`, `deeppavlov.train_model` to install model requirements before interaction with model ([1603](https://github.com/deeppavlov/DeepPavlov/pull/1603)).

Bug Fixes and Other Changes
