cli: Excise `cros_logging` module

Remove all usages of `cros_logging` in chromite/cli and replace them
with the stdlib `logging` module. The NOTICE level is already provided by
the custom Logger subclass initialized in chromite's top level module __init__.py

Update isort.cfg to allow imports from the `abc` and `collections.abc`
modules to be on a single line.

This change was made by finding all imports of `cros_logging` and
replacing those usages with stdlib `logging` and then running `isort`
over all modified files.
