feat: manage litellm secrets engine via terraform-provider-litellmvaultsecret (#83)
## Why
The `vault-plugin-secrets-litellm` engine (mints LiteLLM virtual keys) is registered in Vault, but nothing in this repo declared its mount, config, or roles. This wires in the companion `litellm` provider (`git.unkin.net/unkin/litellmvaultsecret`) so the mount is managed as code alongside the other secret backends.

## Changes
- Add `litellm_secret_backend` module that mounts the engine and writes its config (`base_url`, `request_timeout_seconds`); reads the sensitive `master_key` from KV at `kv/service/vault/<country>/<region>/secret_backend/<path>`, matching the consul/kubernetes backend convention.
- Add `litellm_secret_backend_role` module that manages roles (`models`, `max_budget`, `key_alias_prefix`, `ttl`/`max_ttl` in seconds, `metadata`).
- Register both modules in `vault_cluster` `main.tf` and add typed variables in `variables.tf`.
- Discover `litellm_secret_backend[_role]` YAML in `config.hcl` and pass the maps through the terragrunt inputs.
- Declare the `litellm` provider (pinned `0.1.0`) and a `provider "litellm"` block in the generated root `backend.tf`.
- Add example config for the `litellm` mount and a sample `team-a` role.

## Notes
- Requires the `master_key` KV secret to exist at `kv/service/vault/au/syd1/secret_backend/litellm` before apply (the module reads it, does not create it).
- Assumes provider `git.unkin.net/unkin/litellmvaultsecret` `0.1.0` is published to the artifactapi `terraform-unkin` registry.

terraform-vault

A repository to manage the configuration of Vault secret engines, authentication modes and policies.

Usage

  1. Initialize Terraform

Once you have your backend block configured, you need to initialize your Terraform working directory to configure the backend:

terraform init

This command initializes the backend and checks the connection to Consul. If everything is set up correctly, Terraform will start using Consul as its backend for storing the state.

  1. Common terraform init Errors

If you encounter errors while running terraform init, check the following:

Consul server is reachable: Make sure that the address is correct and that you can connect to the Consul server.
Consul token (if using ACLs): Verify that the token has the correct permissions to write to the specified path in the Consul KV store.
  1. Example Consul KV Structure

In Consul, the state file will be stored in the KV store under the specified path:

terraform/state

You can check the Consul KV store by accessing the Consul UI or using the consul kv command to see the stored Terraform state:

consul kv get terraform/state
