Description

What's the goal of this PR?

audit command should check only specific checks

What changes did you make?

In #712, added new checks args into audit command, but not used.

I change it as string slice variable and change check severity as Ignored when passing checks args.

What alternative solution should we consider, if any?

N/A

QA

before: not filtered checks
