1. Datasource for VMware …

   This patch finally introduces the Cloud-Init Datasource for VMware
   GuestInfo as a part of cloud-init proper. This datasource has existed
   since 2018, and rapidly became the de facto datasource for developers
   working with Packer, Terraform, for projects like kube-image-builder,
   and the de jure datasource for Photon OS.
   
   The major change to the datasource from its previous incarnation is
   the name. Now named DatasourceVMware, this new version of the
   datasource will allow multiple transport types in addition to
   GuestInfo keys.
   
   This datasource includes several unique features developed to address
   real-world situations:
   
     * Support for reading any key (metadata, userdata, vendordata) both
       from the guestinfo table when running on a VM in vSphere as well as
       from an environment variable when running inside of a container,
       useful for rapid dev/test.
   
     * Allows booting with DHCP while still providing full participation
       in Cloud-Init instance data and Jinja queries. The netifaces library
       provides the ability to inspect the network after it is online,
       and the runtime network configuration is then merged into the
       existing metadata and persisted to disk.
   
     * Advertises the local_ipv4 and local_ipv6 addresses via guestinfo
       as well. This is useful as Guest Tools is not always able to
       identify what would be considered the local address.
   
   The primary author and current steward of this datasource spoke at
   Cloud-Init Con 2020 where there was interest in contributing this datasource
   to the Cloud-Init codebase.
   
   The datasource currently lives in its own GitHub repository at
   https://github.com/vmware/cloud-init-vmware-guestinfo. Once the datasource
   is merged into Cloud-Init, the old repository will be deprecated.
