ASTERIXDB-1105 - LICENSE per submodule

This is a good part of what we need to have a specific set of
dependencies per binary assembly. The main key here is using the
maven remote resources plugin, and supplemental resources to
fill in info from the POM of dependencies where it is lacking.
For things that aren't described in Maven dependencies,
like Javascript files, they are added as LICENSE fragments
that get included in binary assemblies.
