Mark Stemm 2352b96d6b Change license to Apache 2.0 (#419)
Replace references to GNU Public License to Apache license in:

 - COPYING file
 - README
 - all source code below falco
 - rules files
 - rules and code below test directory
 - code below falco directory
 - entrypoint for docker containers (but not the Dockerfiles)

I didn't generally add copyright notices to all the examples files, as
they aren't core falco. If they did refer to the gpl I changed them to
apache.
