The Alternator tests can run against HTTPS - namely when using
test/alternator/run with the "--https" option (local Alternator
configured with HTTPS) or "--aws" option (DynamoDB, using HTTPS).
In some cases we make these HTTPS requests with verify=False, to avoid
checking the SSL certificates. E.g., this is necessary for Alternator
with a self-signed certificate. Unfortunately, the urllib3 library adds
an ugly warning message when SSL certificate verification is disabled.
In the past we tried to disable these warnings, using the documented
urllib3.disable_warnings() function, but it didn't help. It turns out
that pytest has its own warning handling, so to disable warnings in
pytest we must say so in a special configuration parameter in pytest.ini.
So in this patch, we drop the disable_warnings call from conftest.py
(where it didn't help), and instead put a similar declaration in
pytest.ini. The disable_warnings call in the test/alternator/run
script needs to remain - it is run outside pytest, so pytest.ini
doesn't affect it.
After this patch, running test/alternator/run with --https or --aws
finishes without warnings, as desired.

This patch avoids an annoying warning
Warning: Unknown config ini key: flake8-ignore
when running one of the pytest-based test projects (cql-pytest,
alternator and redis) on recent versions of pytest.
In commit 2022da2405, we added to the
toplevel Scylla directory a "tox.ini" file with some intention to
configure Python syntax checking. One of the configurations in this
tox.ini is:
[pytest]
flake8-ignore =
E501
It turns out that pytest, if a certain test directory does not have its
own pytest.ini file, looks up in ancestor directory for various
configuration files (the configuration file precedence is described in
https://docs.pytest.org/en/stable/customize.html), and this includes
this tox.ini configuration section. Recent versions of pytest complain
about the "flake8-ignore" configuration parameter, which they don't
recognize. This parameter may be ok (?) if you install a flake8 pytest
plugin, but we do not require users to do this for running these tests.
Moreover, whatever noble intentions this commit and its tox.ini had,
nobody ever followed up on it. The three pytest-based test directories
never adhered to flake8's recommended syntax, and never intended to do
so. None of the developers of these tests use flake8, or seem to wish
to do so. If this ever changes, we can change the pytest.ini or undo this
commit and go back to a top-level tox.ini, but I don't see this happening
anytime soon.
