c4164b3497 Use pre-commit for Git hooks (#3406)
* Initial design of using pre-commit for Git hooks

* Refactor to reuse existing code and provide merge capabilities

* Linter fixes

* More cleanup

* scm: make use_precommit_tool optional

* dvc: install our own hooks

* install: fix typo

* install: fix bugs in pre-commit integration

* install: don't forget 'always_run' for post-checkout

* install: no need to run pre-commit install if conf file doesn't exist

* install: fix bugs

* install: use python hooks

* add .pre-commit-hooks.yaml
