Use different INSTALLATION_TYPE for AWS Marketplace AMI to differentiate them
Right now, all of our AMIs get gitlab-aws-ami
as INSTALLATION_TYPE, which is mapped to the periscope report. We may want to differentiate between community AMIs and Marketplace AMIs.
I propose we change it to gitlab-aws-marketplace-ami
for the AMIs used in Marketplace listing. Yes, this won't make sense for the CE listing since for CE we use the community AMI itself for marketplace listing too. But this working just for EE is still worthy of having.
@ebrinkman @joshlambert WDYT?
