pip need to be installed inside the VM

[mpapply11]

Thank you for putting together all of this. it is so convenient to play with a MySQL cluster with proxy and orchestrator solution.

However, I have encountered the below errors when installing every of the VMs.

"""sudo apt-get install -y python-pip """
