Author: Arvind Shyamsundar <ar...@apache.org>

    Use cloud-init for Azure deployments (#420)
    
    Define and use a cloud-init config which is then passed to the Azure
    instance creation modules as custom data. Currently the only
    per-instance configuration specified is to upgrade the existing CentOS
    packages on the VM. This also provides an interim Azure-specific
    solution to an Azure-specific requirement (as there is not a more recent
    version of CentOS 7.x for Azure). Without this, currently Muchos cannot
    be used to setup a cluster on Azure as the CA certificates are outdated
    and prevent Ansible from downloading tarballs on the proxy host.
    
    Future work will be done to evaluate and potentially use a more modern
    default image for Azure, as well as generalize using cloud-init  across
    both EC2 and Azure cluster types in Muchos.
