* cleanup linters: get rid of pylint-pytest, run pylint only on dvc/ directory, etc.
* remove pylint direcitves
* Apply suggestions from code review
* Update pyproject.toml
- Overriding a config value : foo.bar=value
- Appending a config value : +foo.bar=value
- Appending or overriding a config value : ++foo.bar=value
- Removing a config value : ~foo.bar, ~foo.bar=value

Breaking changes:
To modify a list, `foo[0]=bar` must now be passed as `foo.0=bar`.
Modifying a nested list inside a dictionary is not supported by omegaconf.

* Fix merging of params when empty
Recent release of python-benedict==0.24.1 started ignoring empty dictionaries
during merge. The way we expected to work was questionable and also how
benedict itself tries to handle the references to empty dictionary is
also questionable.
I consider this to be a proper way to handle this even if this gets fixed
on the benedict side.
* Revert "setup: limit python-benedict version (#6377)"
This reverts commit 15de826266.
* add comment for why passing through benedict
* separate validation and transformation of args from add func
* make tests pass for Python3.6
* cleanup
* use dict for attr-access and patch boundarguments.arguments
* pylint: enable attribute-outside-init check
* fix tests
* Fix mock for time
This was an interesting one. I was mocking `time` on function definition
and then, using those later on test run. When all the tests were run, there
would be some delay that'd make tests fail. Hmmm ...
* test: remove never used copy of load_stage_file()
* dvc: save comments and custom formatting in stage files
* Add a couple of TODOs
* test: test repro doesn't clear comments and formatting in .dvc
As part of this I started writing pytest-like tests and added commonly
used fixtures.
* test: simplify and prettify dvc formatting retained test
Also test that line comments after md5 fields are retained.
* test: fix tests
* dvc: fix stage and metrics opens not closed
* dvc: always use utf-8 in stage files
It used to encode in system default encoding. Not sure if PyYAML was
handling this silently or we were just lucky all the way.
* test: unit test apply_diff()
* test: remove TODOs and ASK
* dvc: polish dvc-formatting PR
* dvc: move stage load/dump utils to a new stage utils file
* dvc: clean up apply_diff()
* test: test stage md5 ignores comments
* test: remove pytests starting marker
