[QT-697] enos: add descriptions and quality verification (#27311) 
In order to take advantage of enos' ability to outline scenarios and to
inventory what verification they perform we needed to retrofit all of
that information to our existing scenarios and steps.

This change introduces an initial set of descriptions and verification
declarations that we can continue to refine over time.

As doing this required that I re-read every scenanario in its entirety I
also updated and fixed a few things along the way that I noticed,
including adding a few small features to enos that we utilize to make
handling initial versions programtic between versions instead of having a
delta between our globals in each branch.

* Update autopilot and in-place upgrade initial versions
* Programatically determine which initial versions to use based on Vault
  version
* Partially normalize steps between scenarios to make comparisons easier
* Update the MOTD to explain that VAULT_ADDR and VAULT_TOKEN have been
  set
* Add scenario and step descriptions to scenarios
* Add initial scenario quality verification declarations to scenarios
* Unpin Terraform in scenarios as >= 1.8.4 should work fine

scenario "dev_pr_replication" {
description = <<-EOF
This scenario spins up a two Vault clusters with either an external Consul cluster or
integrated Raft for storage. The secondary cluster is configured with performance replication
from the primary cluster. None of our test verification is included in this scenario in order
to improve end-to-end speed. If you wish to perform such verification you'll need to a non-dev
scenario.
The scenario supports finding and installing any released 'linux/amd64' or 'linux/arm64' Vault
artifact as long as its version is >= 1.8. You can also use the 'artifact:local' variant to
build and deploy the current branch!
In order to execute this scenario you'll need to install the enos CLI:
- $ brew tap hashicorp/tap && brew update && brew install hashicorp/tap/enos
You'll also need access to an AWS account via Doormat, follow the guide here:
https://eng-handbook.hashicorp.services/internal-tools/enos/common-setup-steps/#authenticate-with-doormat
Follow this guide to get an SSH keypair set up in the AWS account:
https://eng-handbook.hashicorp.services/internal-tools/enos/common-setup-steps/#set-your-aws-key-pair-name-and-private-key
Please note that this scenario requires several inputs variables to be set in order to function
properly. While not all variants will require all variables, it's suggested that you look over
the scenario outline to determine which variables affect which steps and which have inputs that
you should set. You can use the following command to get a textual outline of the entire
scenario:
enos scenario outline dev_pr_replication
You can also create an HTML version that is suitable for viewing in web browsers:
enos scenario outline dev_pr_replication --format html > index.html
open index.html
To configure the required variables you have a couple of choices. You can create an
'enos-local.vars' file in the same 'enos' directory where this scenario is defined. In it you
declare your desired variable values. For example, you could copy the following content and
then set the values as necessary:
artifactory_username = "username@hashicorp.com"
artifactory_token = "<ARTIFACTORY TOKEN VALUE>
aws_region = "us-west-2"
aws_ssh_keypair_name = "<YOUR REGION SPECIFIC KEYPAIR NAME>"
aws_ssh_keypair_key_path = "/path/to/your/private/key.pem"
dev_build_local_ui = false
dev_consul_version = "1.18.1"
vault_license_path = "./support/vault.hclic"
vault_product_version = "1.16.2"
Alternatively, you can set them in your environment:
export ENOS_VAR_aws_region="us-west-2"
export ENOS_VAR_vault_license_path="./support/vault.hclic"
After you've configured your inputs you can list and filter the available scenarios and then
subsequently launch and destroy them.
enos scenario list --help
enos scenario launch --help
enos scenario list dev_pr_replication
enos scenario launch dev_pr_replication arch:amd64 artifact:deb distro:ubuntu edition:ent.hsm primary_backend:raft primary_seal:awskms secondary_backend:raft secondary_seal:pkcs11
When the scenario is finished launching you refer to the scenario outputs to see information
related to your cluster. You can use this information to SSH into nodes and/or to interact
with vault.
enos scenario output dev_pr_replication arch:amd64 artifact:deb distro:ubuntu edition:ent.hsm primary_backend:raft primary_seal:awskms secondary_backend:raft secondary_seal:pkcs11
ssh -i /path/to/your/private/key.pem <PUBLIC_IP>

After you've finished you can tear down the cluster
