feat: add support for matchExpressions when filtering for nodes

[miguelvr]

Description, Motivation and Context

Includes the ability to use a Kubernetes matchExpressions label selector for the nodeResources analyzer.

I wanted to write pre-flight checks to analyze nodes that contained a specific label and another that negated it. Currently, this is not possible with the MatchLabel selector. It would be possible with a MatchExpressions label selector by using the negation operators (e.g., NotIn / DoesNotExist)

Many thanks for the contribution @miguelvr!

The changes look good, I will approve it after we fix the failed Github Action.

When we introduce new field in Troubleshoot spec, we have to ensure the schemas are updated accordingly. Please run below command from the project root directory and commit the changes accordingly.

make schemas
make check-schemas

@nvanthao make generate fails locally because it assumes a specific relative path directory structure (that I think it's used in CI, based on the git history)

it seems like the files are not generated to the repo anyway, so I skipped that command and committed everything else.

Let me know if there's something else I should fix on my end

[nvanthao]

Thank you for running the commands and for pointing out the issue with the relative paths. We'll address that separately to ensure smoother local workflows.

Since the schemas were successfully generated by other targets and everything else looks good, I'll go ahead and approve this PR. Many thanks for your contribution!
