aiohttp

Describe the bug

Originally, @asvetlov intended to delete any use of attrs from aiohttp 4.0+ series via aio-libs/aiohttp#5284. He dropped it from the runtime deps too.

But there are some places that still rely on attrs meaning that this will cause failures in runtime because of the missing dep. The tests currently succeed because attrs is listed as a test dep.

As a few Socket Mode related tests started failing only in the GitHub Actions environment, I've disabled them by this commit: slackapi/python-slack-sdk@75b554a

We would like to get the tests back to the running tests in CI builds once we figure out the way to make them stable.

Describe the solution you'd like
I think that it would be a good idea for us to let users set the filename and content-type headers through the Part annotation. Maybe like so:

Should be easy to do and good exercise. Would be cool to have some sort of social auth via github/twitter/google integration.

Some examples:

Currently, we are using the term "event" for both Events API data and any incoming payload requests from Slack in the Bolt document. For example,

• There is the "Listening to events" section: https://slack.dev/bolt-python/concepts#event-listening which is referring to the Events API
• Then there is the "Acknowledging events" section: https://slack.dev/bolt-python/concepts#acknowledge which is

Pickled pure Python MultiDicts should be unpickled as Cythonized if unpicker is executed on machine with Cython support.
And vise versa.

I.e. if you have a variable specified as endCursor but you wrote your query to take lastCursor, it will simply just "work" thanks to apparently GitHub just assuming null for missing variables and not caring about variables that don't line up.

Will be great have approach to put some arguments for make test or commands some like this.

For that we need add some like that into Makefile.

# arguments
FIRST_ARG := $(firstword $(MAKECMDGOALS))
ARGS = $(filter-out $@,$(MAKEOVERRIDES) $(MAKECMDGOALS))
MAKEFILE_PATH := $(abspath $(firstword $(MAKEFILE_LIST)))

%:
	@:

and after that add ${ARGS} to our commands
