Add a warning ``use-implicit-booleaness-not-comparison`` for comparison with collection literals (#5120)
* Create a new checker; use-implicit-booleanness checker where it looks
for boolean evaluatiion with collection literals such as `()`, `[]`,
or `{}`
* Fixed invalid usage of comparison within pylint package
This closes #4774
* Ignore tuples when checking for `literal-comparison`
Closes #3031
* Merge len_checker with empty_literal checker
Moving empty literal checker with len_checker to avoid class without
iterators without boolean expressions (false positive on pandas)
Reference: https://github.com/PyCQA/pylint/pull/3821/files
* Update `len_checker` and its class `LenChecker` to `ComparisonChecker`
to reflect better usage after merging between `len_checker` and
`empty_literal_checker` and its tests.
* Fixed `consider_using_in` and `consider_iterating_dictionary` tests
that were failing due to new empty literal checkers.
