Upgrades dependencies, adds environment bootstrap

[austingebauer]

Overview

This PR upgrades dependencies, tooling, and adds development environment automation. Changes in this PR align this repo with tooling in the Vault plugin scaffold.

Local environment bootstrap usage:

make setup-env
source ./bootstrap/terraform/local_environment_setup.sh
make configure
make teardown-env

Test Results:

$ TESTARGS='-count=1' make test
==> Checking that code complies with gofumpt requirements...
CGO_ENABLED=0 go test ./... -count=1 -timeout=20m
ok      github.com/hashicorp/vault-plugin-auth-azure    0.240s
?       github.com/hashicorp/vault-plugin-auth-azure/cmd/vault-plugin-auth-azure        [no test files]

Note that there aren't acceptance tests that actually use Azure resources in this plugin, so that's omitted from this description.

Contributor Checklist

• Add relevant docs to upstream Vault repository, or sufficient reasoning why docs won’t be added yet
• Add output for any tests not ran in CI to the PR description (eg, acceptance tests)
• Backwards compatible

I still need to update the readme. Will do that tomorrow.

After fixing my ssh key env this terraform setup and tests all worked great!

Waiting on helpdesk to get access to an Azure account to test the full setup but it looks good!

I'd be curious to know which makefile vars & targets are deprecated. I hesitated to remove stuff like quickdev, testcompile & others because I wasn't sure if it was part of some CI. But if we know for some it's not part of anyone's wofkflow I'd add the Makefile clean-up in the ACs of the engineering improvement initiative.

LGTM, important comments are addressed and as for:

• TF resource naming
• leaving the required_provider block
• provisioning resources for both identify types at all time
  These are more questions/observations than suggestions. Happy to chat if you have questions.
