Extended verify command with runner selector

What does this MR do?

This MR implements runner selectors in verify command.

In case of errors it will terminate with non-zero exit code.

Why was this MR needed?

This improvement has been scheduled for %v9.1 milestone with #2171 (closed) and #2073 (closed)

Are there points in the code the reviewer needs to double check?

I tried to stick with the principle of least surprise regarding non-zero exit code strategy.

• If any of the verified runners failed the check, it returns non-zero unless you asked to delete
• If a filtering parameter is issued and it didn't match any runner, non-zero is returned
  • this has the side effect that asking to verify an empty configuration will always return non-zero

Does this MR meet the acceptance criteria?

• Documentation created/updated
• Tests
  • Added for this feature/bug
  • All builds are passing
• Branch has no merge conflicts with master (if you do - rebase it please)
