[RFE] Allow marking lint jobs as nonfatal

[Qalthos]

see also ansible-network/github_actions#80
vyos/vyos.vyos#315 shows it in use

This might also be applicable to other scenarios, but particularly with ansible-lint, new rules may cause new errors that need not block all PRs as soon as they show up.

If someone needs to run an environment but ignore the errors, I think what we can do is add a key to the [ansible] section of the ini, something like this:

[ansible]

ignore_errors=
         devel
         sanity-py3.10-2.9

when building the commands we could preface them with a -

at the same time we should probably add support for using a generative env_list

I should note that we don't currently generate an environment for running ansible-lint but I think that too would be a neat addition.

v1 had a lint_all target that ran yamllint, ansible-lint, and I think flake8, if memory serves correctly. It also provided a mechanism to pass command line arguments to each of those commands. If we are strictly going to reach feature parity, then we should plan to supply this.

However, it might be better to instead just point people towards using pre-commit and not force a particular set of lint commands. We could provide a default pre commit configuration and make sure that all of the tools support appropriate hooks.
