Add script to auto-generate Bazel project file
Which is much faster to sync since it reduces the scope of the IDE
targets to java libraries. Although, it requires one to execute the
script each time a new app/library is added to the source tree.
Example usage:
onos-gen-bazel-project > .bazelproject
