Add checks

Adds lb-ap check to run checks as defined in lbapcommon!24 (merged). The same checks are performed at the end of lb-ap test.

Still to do:

• Fix calling of the check functions, ensure they're passing for a test production
• Add the new checks proposed in lbapcommon!27 (merged)
• Add some tests

(FYI @cburr @gtuci )
