Add missing pom.xml files

Add missing modules to top level pom.xml and add missing
pom files for core, adaptors, northbound and plugin directories.
Also rolled version to next minor version (1.2.0-SNAPSHOT) to avoid
conflict with compiled code from individual repos during
transition to new structure.
