Check opened issues before tests running

[evgeniiz321]

If there is an open issue with the test name in it's description, e.g. an issue in the rest gateway because of which some tests (test_put_with_bearer_when_eacl_restrict) fail, we need a way to understand it from the test itself and skip this test.

Describe the solution you'd like

Add a custom hook that will be called during pytest test collection phase. This hook will need to go to github and parse opened issues for projects - neofs-node/neofs-s3-gw/neofs-rest-gw.
There should be a certain field in issues' descriptions to be parsed by this hook.

Very fragile to me.

The other way is just to manually update tests and add skips for tests with opened issues. This is not very convenient either and leads to almost useless PRs or just to failed tests. It should be done somehow automatically. But I do not see any other way how to link a github issue to a test besides the description field.
