Add go system buildpack
Update go buildpack submodule
Remove etcd_leader job

* Provide each etcd instance with all other etcd IPs
* loggregator.etcd_ips -> etcd.machines
* hm9000.etcd_ips -> etcd.machines

Replace leader job with an additional etcd_z1 instance
in templates. Had to use an additional static ip for this
instance so as not to conflict with the old leader job
during deploy.

Java Buildpack 2.1

Starting with the 2.1 release of the Java Buildpack, packaged versions
of the buildpack should not be linked via submodule.  Instead, a
packaged version of the buildpack, (complete with version baked into
the code) should be used.

To facilitate both Cloud Foundry open source and PivotalCF, there are
two different versions of the buildpack.  The first, online buildpack,
should be used in environments that have Internet access (e.g.
https://run.pivotal.io).  The second, offline buildpack, should be
used in environments that do not have Internet access (e.g.
PivotalCF).

This change removes the existing Java Buildpack submodule and replaces
it with a reference to the packaged buildpack in the blobstore.  This
packaging style was based on the gloang packaging that already
existed.
