Skip yamllint warnings

[dthomson-triumf]

Hi, I saw that #1794 was marked with a "good first issue" tag, so I thought I'd try doing a small fix for this bug that I just ran up against.

The PR should be fairly straightforward to read, though I'm not sure if this is along the lines of what you might be looking for with a solution. Comments, suggestions and concerns are all welcome.

Thanks!

@dthomson-triumf I do have the impression that you are trying to fix something that does not need to be fixed.

As far the linter is concerned any message from yamllint is an error. We do not care if yamllint is configured to treat them as errors or warnings, for us all of them are violations.

If you want to make ansible-lint to treat a specific yamllint rule as a warning, you can add these to warn_list as yaml[some-rule] and it should work.

I thought that #1794 indicated that this was a bug that needs fixing?

Regardless, using the yaml[some-rule] entry in the warn_list doesn't seem to work for me with ansible-lint 6.3.0 and yamllint 1.27.1, but maybe I'm misunderstanding something.

The following setup:

# playbook.yml
---
- hosts: localhost
  tasks:
    - name: Here is a long task
      ansible.builtin.command: echo "This is the output from a very long command that's not going to make ansible-lint very happy"
      changed_when: false

# .ansible-lint
---
warn_list:
  - yaml[list-length]

# .yamllint
---
rules:
  line-length:
    level: warning
    max: 80

Still gives me:

me@myhost:~/ansible-lint-warns$ ansible-lint 
WARNING  Listing 1 violation(s) that are fatal
yaml: line too long (130 > 80 characters) (yaml[line-length])
playbook.yml:5

You can skip specific rules or tags by adding them to your configuration file:
# .config/ansible-lint.yml
warn_list:  # or 'skip_list' to silence them completely
  - yaml  # Violations reported by yamllint.

Finished with 1 failure(s), 0 warning(s) on 1 files.

Only using:

warn_list:
  - yaml

Treats the yamllint issues as warnings, but that means every single reported result from yamllint, including those that are being listed as errors and not just warnings will be treated as warnings by ansible-lint.
