* 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. Signed-off-by: Ryan Cragun <me@ryan.ec>
