Migrates CaloMoniDst to Functional

This MR migrated all class in the Calo/CaloMoniDst package to the new Gaudi::Functional.

List of non-trivial changes

• There was a base class CaloNtpBase which intended to be a base class for other ntuple algo (according to the doc/release.notes). However, upon inspection, there were only 4 classes eligible, and only one of them is subclassing CaloNtpBase. Those 4 classes does not seem to be similar enough to warrant a base class, and the C++11 syntaxes and Gaudi::functional::Consumerremoves LOTS of boilerplate codes already, so the base class CaloNtpBase is removed and those 4 classes now inherit directly from Consumer.
• The need to keep the same configurable keys, Input and Inputs, is also taken into the consideration during the refactoring. Most of the classes adjust these 2 fields at the configuration-time (such that Input usually refers to a single relation table, whilst Inputs to possibily-many list of TES containers). The keys thus retain the same name when subclassing from Consumer, and for consistency the aliasing (using) statement also do the same of readability.
• New file CaloMoniUtils was added to provide common utility functions, instead of the stateful CaloNtpBase.

The rest of the changes are c++11 modernisation to the code, a la Gerhard's style.
