Add opencontrail networking provisioning support in kubernetes salt based provisioning

Browse Source 
OpenContrail is an open-source based networking software which provides virtualization support for the cloud.

This change-set adds ability to install and provision opencontrail software for networking in kubernetes based cloud environment.

There are basically 3 components

o kube-network-manager -- plugin between contrail components and kubernets components
o provision_master.sh -- OpenContrail software installer and provisioner in master node
o provision_minion.sh -- OpenContrail software installer and provisioner in minion node(s)

These are driven via salt configuration files

One can provision opencontrail by just setting "export NETWORK_PROVIDER=opencontrail"
Optionally, OPENCONTRAIL_TAG, and OPENCONTRAIL_KUBERNETES_TAG can be used to
specify opencontrail and contrail-kubernetes software versions to install and provision.

Public-IP Subnet provided by contrail can be configured via OPENCONTRAIL_PUBLIC_SUBNET
environment variable

At this moment, plan is to add support for aws, gce and vagrant based platforms
