add SessionAuthHandler

[mishaschwartz]

Add weaver.cli.SessionAuthHandler class which uses the cookies stored in a pre-existing requests.Session instance to authenticate.

Alternative to #597 as discussed in #597 (comment)

Closes #597

[mishaschwartz]

Ok, here's the new usage:

CLI:

weaver processes -aC weaver.cli.CookieAuthHandler -aT 'auth=thecookievaluethattshouldbeincluded' --url https://example.com/weaver

Client

s = requests.Session()
# add cookies to the session
client = WeaverClient("https://example.com/weaver", auth=CookieAuthHandler(token=s.cookies.get_dict()))

[mishaschwartz]

Note that because I made the changes in the RequestAuthHandler as discussed:

It would be fine with adding a pre-check to RequestAuthHandler that skips request_auth call when the token/cookie is predefined in the handler

it is possible to send a token to the BearerAuthHandler as well in a similar way (if you have the bearer token already)

Thanks for the new feature (waiting for the tests to run/succeed before merge).
