Added bootstrap commands & reusable acc test workflow

[maxcoulombe]

Overview

Added reusable workflow for acc tests

Development flow becomes:

• make setup-env
• source ./bootstrap/terraform/local_environment_setup.sh
• Code your feature or bug fix
• make configure
• Test your modifications through vault commands or run the acceptance tests with make acctest
• You can quickly iterate by running make configure after any code modification to update your local Vault instance with the latest changes

Full run:

user:~/projects/vault-plugin-database-redis$ make setup-env

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
