* 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.

Add `config_mode` variant to some scenarios so we can dynamically change
how we primarily configure the Vault cluster, either by a configuration
file or with environment variables.
As part of this change we also:
* Start consuming the Enos terraform provider from public Terraform
registry.
* Remove the old `seal_ha_beta` variant as it is no longer required.
* Add a module that performs a `vault operator step-down` so that we can
force leader elections in scenarios.
* Wire up an operator step-down into some scenarios to test both the old
and new multiseal code paths during leader elections.
