Add consul_template role files from master branch

- Added all files from consul_template-legacy and consul_template-org roles
- These roles are now regular directories instead of submodules

+#consul_template
+
+An Ansible role to install and configure HashiCorp’s consul-template, securely fetching TLS certificates and private keys\
+from HashiCorp Vault using AppRole authentication, rendering them to disk, and reloading services when certificates change.
+
+### Requirements
+	•	consul-template binary downloaded from HashiCorp releases.
+	•	Network connectivity from the target host to the Vault instance (vault_address).
+	•	Appropriate Vault AppRole credentials (vault_approle_role_id, vault_approle_secret_id) provisioned by Terraform or other automation.
+
+### Role Variables
+
+The following variables are required and should be set either through inventory or as role parameters:
+
+ | Variable	               | Description                                                | Default |
+ | vault_address           | URL of your HashiCorp Vault instance                       | None (required) |
+ | vault_approle_role_id   | Vault AppRole Role ID for consul-template authentication   | None (required) |
+ | vault_approle_secret_id | Vault AppRole Secret ID for consul-template authentication | None (required) |
+ | environment             | Environment identifier (e.g., prod, nonprod)               | None (required) |
+ | short_hostname          | Short hostname of the target server (used in file naming)  | None (required) |
+
+### Dependencies
+
+No direct Ansible Galaxy role dependencies. However, it relies on Terraform to provision AppRole credentials and Vault secrets.
+
+### Example Playbook
+
+Example playbook demonstrating basic role usage:
+
+```yml
+- hosts: webservers
+  become: true
+  roles:
+    - role: consul_template
+      vars:
+        vault_address: "https://vault.example.com:8200"
+        vault_approle_role_id: "{{ vault_approle_role_id }}"
+        vault_approle_secret_id: "{{ vault_approle_secret_id }}"
+        environment: "prod"
+        short_hostname: "web01"
+```
