Use vagrant-service-manager way to provision services in Vagrantfile instead of shell provisioner

[brgnepal]

Hi,

I think it's time to introduce vagrant-service-manager configuring services way to provision services in Vagrantfiles.

Right now it is pretty stable and I recommend to provision services this way.

This will remove few lines and give vagrant clean way.

Config lines would be:

 # Openshift
config.servicemanager.services = 'openshift'

# Docker
config.servicemanager.services = 'docker'  or even not required

# Kubernetes
config.servicemanager.services = 'kubernetes'

Few pros:

• Docs become easy for proxy feature as we need not to tell user to delete the shell provisioner and use 'service-manager' way to get start with proxy.
• Kubernetes environment setup is tightly tied with this line
• Vagrantfile becomes thin

We can go ahead with this approach after complete testing and making sure this approach works.

@budhrg let's do all different kind of testing and roll it out. I think now even VSM have proxy specific variable.

@budhrg You should go ahead and send PRs for it and we can test it out.
