Add support for AWS Ec2 IMDSv2

Details

    Description

      In order to patch a vulnerability, Amazon came up with a new version of their metadata service.

      It's no longer unrestricted but now requires a token (in a header), in order to access the metadata service.
      See https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/configuring-instance-metadata-service.html for more information.

      Cassandra currently doesn't offer an out-of-the-box snitch class to support this.
      See https://cassandra.apache.org/doc/latest/operating/snitch.html#snitch-classes

      This issue asks to add support for this as a separate snitch class.
      We'll probably do a PR for this, as we are in the process of developing one.
