Even though this looks like an independently runnable script, it
should not be run independently: a SHA-256 mismatch will fail to stop
the script, unless it was sourced from another script that has ‘set
-e’.

There is only one PostgreSQL database; the "appdb" is irrelevant.
Also use "postgresql," as it is the name of the software, whereas
"postgres" the name of the binary and colloquial name. This is minor
cleanup, but enabled by the other renames in the previous commit.
This moves the puppet configuration closer to the "roles and profiles
method"[1] which is suggested for organizing puppet classes. Notably,
here it makes clear which classes are meant to be able to stand alone
as deployments.
Shims are left behind at the previous names, for compatibility with
existing `zulip.conf` files when upgrading.

There was likely more dependency complexity prior to 97766102df, but
there is now no reason to require that consumers explicitly include
zulip::apt_repository.
The previous steps for standing up a new host were somewhat manual.
This further scripts the process, by using the AWS CLI to start the
instance, and pass it a "user data" script to provision itself upon
boot. This results in a hands-off provisioning process which
completes in 5min.
Additional settings are required for `~/.zulip-install-server.conf`.
It is not suited for all roles, as it assumes one instance type and
security group value. Additionally, not all of the post-provision
process is currently automated -- Nagios SSH key verification, for
instance, is still a manual step. There are also additional steps for
database or frontend servers. Regardless, this is a move toward
automated provisioning.
More modern Linux versions like Bionic will block this, and what we
actually want to do is just run the code in our <<EOF block via bash,
so we should do that explicitly.
