Consider including `ec2-instance-connect` package in AWS MP AMIs

[JedMeister]

I note that Debian (and therefore TurnKey) are listed as supported OS for the use of EC2 Instance Connect. It appears that on Ubuntu it is provided by a package named ec2-instance-connect. Unfortunately it does not appear to be in the Debian repos (I assume why Debian isn't supported). I'm not 100% sure what the rationale for that is, but perhaps we could consider adding it.

FWIW I did download the upstream source (aws-ec2-instance-connect-config) and tried building it on TurnKey (via pool) but it failed, ending with this output:

downgrading this to wishlist as a closer looks makes me think that this isn't something that would be relevant to most of our users...
