chore(e2e): Clean up enos variables

[moduli]

Description

This PR makes all other currently required enos variables either optional or obsolete in order to reduce the amount of setup needed to use the tool.

A previous PR removed the need for aws_ssh_private_key_path and aws_ssh_keypair_name: #6583.

This PR removes the need for

• local_boundary_dir
• local_boundary_src_dir
• local_boundary_ui_src_dir
• boundary_edition
• debug_no_run

This is achieved by doing the following

• local_boundary_dir is now programmatically determined by running which boundary
• local_boundary_src_dir is now programmatically determined by running git rev-parse --show-toplevel
• local_boundary_ui_src_dir was removed (it wasn't needed)
• boundary_edition is now programmatically determined by running make edition
• debug_no_run has been replaced by is_ci, which will be set in github actions workflows. This will trigger the e2e tests to automatically run after creating infra.

Now, you can start enos scenarios without needing to configure anything in enos.vars.hcl (assuming you have the dependencies installed (e.g. enos cli, terraform, go).

cd ~/Developer/boundary
enos scenario launch e2e_docker_base builder:local

Enterprise-changes were tested in https://github.com/hashicorp/boundary-enterprise/pull/2354 and will be cherry-picked into the ce -> ent merge pr.

Pull request overview

This PR refactors Enos e2e scenarios/modules to reduce reliance on manually-supplied variables by deriving values (Boundary edition, repo root, binary path) and generating SSH keys, while also standardizing SSH transport inputs across AWS modules.

Changes:

• Replace/clean up scenario variables by introducing helper modules (get_boundary_edition, get_repo_root, get_binary_path, SSH keypair modules).
• Update AWS modules and scenarios to pass explicit SSH private_key_path/keypair inputs instead of relying on a global Enos provider transport block.
• Adjust license handling to be edition-aware and simplify scenario wiring around license inputs.
