Adapt to new Gaudi Monitoring
This depends on gaudi/Gaudi!1112 (merged) and should not be merged before it.
It's built on top of !2754 (merged) and co (Rec!2204 (merged), Brunel!1068 (merged), Phys!781 (merged), Analysis!700 (merged)) and should not be merged before them either.
It goes together with Lbcom!506 (merged), Boole!312 (merged), Rec!2209 (merged), Brunel!1074 (merged), Phys!796 (merged), Allen!436 (merged), Moore!618 (merged), Analysis!701 (merged), DaVinci!433 (merged), Panoramix!79 (merged), Online!415 (merged), Gauss!662 (merged) which brings a few more dependencies, namely Rec!2204 (merged), Brunel!1068 (merged), Phys!781 (merged), Analysis!679 (merged), Analysis!689 (merged), Analysis!700 (merged) which should all be merged first.
It adapts to various changes among which :
- drop of StatPrint property
- introduction of Monitoring::Hub
