Move tosca-controlloop src directries to new modulestosca-poc

This is the second stage of the TOSCA Controlloop merge.

In this review, the src directories of the old tosca-controlloop modules
are moved to the new modules off the root of the clamp repo and the
pom.xml files are updated with dependencies to allow the build of the
moved modules to run.

So the changes are renaming of files and updates of POM files in the
modules to which src directories are added so that the build works, and
of course deletion of the tosca-controlloop directory and its sub-
modules

The third and final review will follow this, which will merge the
tosca-poc branch onto master, in effect merging this review to master.

The differences with the clamp master repo are shown here:
