Refactor Template by moving suggestions into VCPETemplateSuggestor.

VCPETemplateSuggestor is the one reading from the properties file.
The code in VCPETemplateSuggestos has been improved.
VCPE build model loads BoD physical client interfaces from given logicalInfrastructure.

getLogicalInfrastructure now supports given physical infrastructure not including BoD physical client interfaces.
VCPE logical suggestion includes core lo interface.
Test for vcpe template.

It tests suggestions and builModel include all elements in the template.
It tests also that physicalSuggestion elements have name.

TODO: Tests do not include links nor VRRP and BGP config.
TODO: A test for logicalSuggestion completeness (all fields are suggested) should be created too.
