allow to determine the flavour of the used model to setup the execute-mojo for
that model in a way so that proper maven can execute it as well.

still needs each polyglot extension to pass in the options-map to do it right.
fallback is the old behaviour.

biggest issue here is the VERSION of the plugin which is hardcoded - maybe there is a better way to do it or it is just OK since the plugin might see a different release cycle.
fix the mockup to obey the extended interface from tesla-polyglot-common
externalize some GAV constants which are needed here and there
use the install with options of the execute manager to generate the proper model
get the classloader right especially when polyglot get launched via jruby runtime embedding maven
get more models object handled properly and added special handling for some java model classes
get some more systemtic tests in place
use the version from the actual project for ITs
determine when to load the nativePom for the tasks definitions
added license header
added another utility method
fix the phase setup
use new version
use common utility method
new versions
sync with maven-tools specs
