* terraform: remove modules in repo
These are not currently being maintained and tested, and were
created prior to the existence of the Terraform Module Registry,
which is the more appropriate way to share and distribute modules.
In an effort to limit confusion of the purpose of these modules and
not encourage usage of something we aren't confident about, this
removes them from this repository.
You can still access these modules if you depend on them by pinning to
a specific ref in Git.
It is recommended you pin against a recent major version where
these modules existed:
```
module "consul-aws" {
source = "git::https://github.com/hashicorp/consul.git//terraform/aws?ref=v1.4.0"
}
```
More detail about module sources can be found on this page:

* terraform: add a readme for anyone who can't find the modules
This change started out as a quick update to RHEL 7 support (aka systemd), in
the process I realized most of the other platforms could use an update. While
trying to cleanup there I discovered I was repeating of bunch of information
that might be better maintained in one place - as a result:
* consolidated server.sh and install.sh
* removed upstart-join.conf in a favor of join flag in the consul start
* removed platform specific folders and increased complexity of install.sh to
include handling the differences
* updated and extracted consul version
* added a consistent ip_table.sh file to open ports on firewalls
* updating consul service management configurations to enable proper restarting behavior for each platform
* the configuration naming convention is <distro_origin>_file_name
* added platform to the security group name so you can easily launch multpile platforms at once
* fixes#1304
