fix(contrib): use 1GB per VM

Most modern laptops have ~8GB of memory available to them. On OSX,
this is stretched even thinner due to boot2docker. Lowering the memory
requirement for each host back to CoreOS' default memory requirements
should allow us to use Vagrant on machines with less than 16GB of
memory.

docs(openstack): fix instructions

The openstack instructions were a mix of new/old commands and
wouldn't work on a lot of openstack installs.

These documentation and changes to the provisioning script should
allow for more variation in openstack installs.

This has been tested as working against both a Havana and Juno release
of Openstack.
