Fix IPMI exporter sudo config, add dependency on saz/sudo

[treydock]

Pull Request (PR) description

The sudo config that was in previous code isn't actually valid and this module was just deploying a file with no validation. I added a dependency on saz/sudo so that proper sudo validation can be performed to avoid deploying broken configuration files. I opted to make it a soft dependency so not added to metadata.json.

Seems to be some issues with the tests that need resolved though I'm +1 for this approach.

If this works with adding the --ignore-dependencies when installing the sudo module and contains a link/comment, that's good with me to move this along without waiting on saz.

I updated to use --ignore-dependencies and added a comment pointed at merged but not released pull request to bump stdlib dependency range in the saz/sudo module.

The tests are now failing for postfix exporter, looks like installing one module with --ignore-dependencies breaks future module installs even if that new module you are installing is fine. For now I've just pinned the sudo module to older version that doesn't have max stdlib constraint.

That appears to have fixed the tests
