Changes to read trigger menu JSON from metadata
This MR contains quite scattered changes needed in order to read in the HLT(and L1 - but I have not tested this) menus directly from the in file metadata.
The HLT & L1 menu is in place. Prescales were not present in the file that I rested over (reprocessing file from about a month ago).
I have made necessary changes to the min bias monitoring to use this feature. Existing unit test (and I believe realistic worksflows) using older AODs that are meant for testing CA JOs fails. Missing JSON menu data. What should we do about those?
