Title:
  Configure networking based on EC2 metadata source

Status in cloud-init:
  Confirmed
Status in cloud-init package in Ubuntu:
  New

Bug description:
  EC2 metadata[1] presents information regarding network devices (mac,
  name, etc) that would be useful to consume.  Chiefly we could match
  the network device names surfaced in the EC2 UIs (eth0, eth2...)
  rather than using our own enumeration at boot.

  A method to detemermine if we are on an instance in EC2 as been
  published[2] as part of their documentation so we can now do this in
  the EC2 datasource without impacting clouds that have copied that
  datasource.

  The work done for DO datasource[3] would be applicable here as a
  model.
