Title:
  Use IMDSv2 instead of IMDSv1

Status in ec2-hibinit-agent package in Ubuntu:
  New

Bug description:
  Affected versions:

  Bionic - 1.0.0-0ubuntu4~18.04.6
  Xenial - 1.0.0-0ubuntu4~16.04.4

  IMDSv2 is a protocol that Amazon maintains to access instance
  metadata. IMDSv1 uses a request/respond method, whereas IMDSv2 uses a
  session-oriented method.

  IMDSv2 is a more secure protocol and is recommended going forward.

  instance-metadata-service.html
