E2E with HCP Consul/Vault (#12267)
Use HCP Consul and HCP Vault for the Consul and Vault clusters used in E2E testing. This has the following benefits:

* Without the need to support mTLS bootstrapping for Consul and Vault, we can simplify the mTLS configuration by leaning on Terraform instead of janky bash shell scripting.
* Vault bootstrapping is no longer required, so we can eliminate even more janky shell scripting
* Our E2E exercises HCP, which is important to us as an organization
* With the reduction in configurability, we can simplify the Terraform configuration and drop the complicated `provision.sh`/`provision.ps1` scripts we were using previously. We can template Nomad configuration files and upload them with the `file` provisioner.
* Packer builds for Linux and Windows become much simpler.

tl;dr way less janky shell scripting!

# Bootstrapping Nomad ACLs:
# We can't both bootstrap the ACLs and use the Nomad TF provider's
# resource.nomad_acl_token in the same Terraform run, because there's no way
# to get the management token into the provider's environment after we bootstrap.
# So we run a bootstrapping script and write our management token into a file
# that we read in for the output of $(terraform output environment) later.
