GenericConnectionhandler redesign of internal structures

[andreagilardoni]

The objective of this PR is to make the implementation of the various connection handler more generic.

with this change it was possible to create a GenericConnection handler that is able to be instantiated in conditions where the kind of connection has to be decided at runtime.

Testing connection handler
