WIP: Add filter management to Luxid, add RAPI and CLI interfaces
Query.Filter: Add `evaluateFilterJSON`

We will need it to evaluate filters on OpCodes for job filtering.
JSON: Add `nestedAccessByKey` and `nestedAccessByKeyDotted`

We will need them for job filters, where we want to access OpCodes
as a JSON structure.
qa_utils: Make AssertCommand return stdout/stderr as well

This is usefull if the run commands output something that's needed afterwards.
WIP: Implement job filtering
Tests: Add test for filterRuleOrder

Property mirrors the implementation, but is tested still since it
is an important part of the specification.
