Draft: adapt to const-correct IUpdataManagerSvc interface

Make sure that clients can register a dependency on a (pointer to) const object, and thus do not have to keep pointers non-const instances of their dependencies...

• add some const
• remove some inline
• prefer find_if

must be applied in conjunction with gaudi/Gaudi!1163 (closed) (which may be tricky to do in practice!)

added thread safety label
