dist: drop deprecated AMI parameters on setup scripts

Since we moved all IaaS code to scylla-machine-image, we nolonger need
AMI variable on sysconfig file or --ami parameter on setup scripts,
and also never used /etc/scylla/ami_disabled.
So let's drop all of them from Scylla core core.

Related with scylladb/scylla-machine-image#61

Closes #12043
