[EPIC] Update connectors' code quality to make it pass all the checks

[sergei-solonitcyn]

We now have a configured tool to run some automatic checks of code quality. It can be run with invoke command from airbyte-integrations/connectors/ directory. See its inline help.
The purpose of this epic is to have all the checks to be passed for every connector. So invoke all-checks -c <connector_name> has to return zero exit code.
In case we found any difference between configurations of this tool and pre_commit, that has to be solved before.

When you say "checks of code quality" do you mean linters?

[sergei-solonitcyn]

Yes, linters, tests and test coverage
