[Feature] Allow deploying from a given AMI image

[kpouget]

Would be nice to be able to deploy the CRC/SNC with a given AMI image ID, instead of letting mapt search from it.

I currently do this with this hacky code:

	// Get AMI
	amiID := os.Getenv("CUSTOM_AMI_ID")
	var ami *ec2.LookupAmiResult
	var err error
	if amiID == "" {
		logging.Info("CUSTOM_AMI_ID not set, searching for the right AMI in AWS ...")
		ami, err = amiSVC.GetAMIByName(ctx,
			fmt.Sprintf("%s*", amiName(r.version, r.arch)),
			[]string{"self", amiOwner},
			map[string]string{
				"architecture": *r.arch})
		if err != nil {
			return err
		}
	} else {
		ami = &ec2.LookupAmiResult{
			Id: amiID, // Your custom AMI ID
		}
	}

which allows me to launch

CUSTOM_AMI_ID=ami-... out/mapt aws openshift-snc create ...

but that could be made more user-friendly

Yeah the only caveat is that this will not work with --spot as you do not know on which region will be deployed

[kpouget]

a solution might be to allow restricting the spot instance search to a single region?
as it happens, I've used this trick extensively in the last few weeks, and my instance has always been created in the same AWS region

being able to create my AMI image as a simple update of an existing one (using this ansible script) saved me hours of deployment time
