* VAULT-28146: Add IPV6 support to enos scenarios
Add support for testing all raft storage scenarios and variants when
running Vault with IPV6 networking. We retain our previous support for
IPV4 and create a new variant `ip_version` which can be used to
configure the IP version that we wish to test with.
It's important to note that the VPC in IPV6 mode is technically mixed
and that target machines still associate public IPV6 addresses. That
allows us to execute our resources against them from IPV4 networks like
developer machines and CI runners. Despite that, we've taken care to
ensure that only IPV6 addresses are used in IPV6 mode.
Because we previously had assumed the IP Version, Vault address, and
listener ports in so many places, this PR is essentially a rewrite and
removal of those assumptions. There are also a few places where
improvements to scenarios have been included as I encountered them while
working on the IPV6 changes.

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
