[Merge] ~mitchdz/ubuntu/+source/ec2-hibinit-agent:add-IMDSv2-mantic into ubuntu/+source/ec2-hibinit-agent:ubuntu/devel

[Mitchell Dzurick]

For a little extra information,

After creating an EC2 instance configured correctly you can add my PPA to test, and if you see `Running: swapoff /swap-hibinit` from the agent service and upgrade then that likely means everything is good. 


$ sudo add-apt-repository ppa:mitchdz/ec2-hibinit-agent-add-imdsv2-support

>From this point, start a daemon process and then initiate hibernation, start the machine, and the daemon process should still be running. I do provide an example daemon process to use in the parent bug report.
