Added support for dotted notation references to tasks

[pahrohfit]

• Tasks can be defined/referenced by str dotted notation: "mypkg.module.function" in all places (setup, cron, enqueue_me, etc). Makes setup a bit easier, as well as more uniform across the board (old methods still work)
• Migrated to pyproject.toml based package config
• Migrated development (and workflows) to use poetry
• Added support for redis > 4.3 (includes current 4.4 and 4.5) and adjusted associated requirement restraint
• Added some working str examples to the existing examples
• Cleaned up some minor code annoyances
• Updated workflow versions to current for python/poetry

To setup poetry (exit outta your venv first): poetry install To run unit tests: poetry run poe unittest To run checks: poetry run poe run_checks

All checks are complete and passing.

The python-ci.yml workflow needs testing under your repo, but should work as is.

i don't want poetry, can you split out the features from this?

[tobymao]

there are too many changes that i'm not sure i want. can you please split them out so that i can review them separately?

i really appreciate the effort you put into this. thanks.
