Introduce plugin initialization phase and consolidate config handling

- Added `initialize_plugins` method to `PluginManager` for requesting and processing file system resources during plugin initialization.
- Introduced `InitializationResult` and `ResourceRequest` structures for fine-grained resource management (e.g., directories, files).
- Enhanced configuration injection by separating `global_configs`, `defaults_configs`, and backend-level `haproxy_config`.
- Updated existing plugins (e.g., JWT Validator, Cloudflare) to use the initialization phase for resource setup.
- Simplified domain plugin execution by consolidating configuration logic into unified loops.

+## Environment Variables
+
+**New in v2.0:** Plugins can use environment variables for configuration.
+
+### Core Environment Variables
+
+- `EASYHAPROXY_PLUGINS_DIR` - Override plugin directory (default: `/etc/haproxy/plugins`)
+- `EASYHAPROXY_PLUGINS_ENABLED` - Comma-separated list of enabled plugins
+- `EASYHAPROXY_PLUGINS_ABORT_ON_ERROR` - Abort on plugin errors (default: `false`)
+
+### Plugin-Specific Environment Variables
+
+- `EASYHAPROXY_PLUGIN_<PLUGIN_NAME>_<CONFIG_KEY>` - Configure plugin settings
+
+**Example:**
+```bash
+EASYHAPROXY_PLUGINS_ENABLED=jwt_validator,cloudflare
+EASYHAPROXY_PLUGIN_JWT_VALIDATOR_ALGORITHM=RS256
+EASYHAPROXY_PLUGIN_JWT_VALIDATOR_ISSUER=https://auth.example.com/
+EASYHAPROXY_JWT_KEYS_DIR=/custom/path/jwt_keys  # Plugin-defined env var
+```
+
+### Plugin Resource Directories
+
+**New in v2.0:** Plugins can make their resource directories configurable via environment variables.
+
+**Example:**
+```python
+class MyPlugin(PluginInterface):
+    def __init__(self):
+        # Make resource directory configurable
+        self.data_dir = os.getenv("EASYHAPROXY_MY_PLUGIN_DATA_DIR", "/etc/haproxy/my_plugin_data")
+
+    def initialize(self) -> InitializationResult:
+        return InitializationResult(
+            resources=[
+                ResourceRequest(resource_type="directory", path=self.data_dir)
+            ]
+        )
+```
+
+---
+
 ## Best Practices
 
-### 1. Error Handling
+### 1. Use Plugin Initialization for Resource Setup
+
+**[New in v2.0]** Use the `initialize()` method to request file system resources.
+
+**Do:**
+```python
+def initialize(self) -> InitializationResult:
+    return InitializationResult(
+        resources=[
+            ResourceRequest(resource_type="directory", path=self.data_dir)
+        ]
+    )
+
+def process(self, context: PluginContext) -> PluginResult:
+    # Directory already exists, just use it
+    filepath = os.path.join(self.data_dir, "data.txt")
+    with open(filepath, 'w') as f:
+        f.write("data")
+```
+
+**Don't:**
+```python
+def process(self, context: PluginContext) -> PluginResult:
+    # Creating directories in process() is inefficient
+    os.makedirs(self.data_dir, exist_ok=True)  # Called on every execution!
+    filepath = os.path.join(self.data_dir, "data.txt")
+```
+
+### 2. Use Typed Result Fields for Config Injection
+
+**[New in v2.0]** Use `global_configs` and `defaults_configs` fields instead of metadata.
+
+**Do:**
+```python
+return PluginResult(
+    haproxy_config="use-fcgi-app fcgi_example",
+    global_configs=["fcgi-app fcgi_example\n    docroot /var/www"],
+    defaults_configs=['log-format "..."']
+)
+```
+
+**Don't:**
+```python
+# Deprecated: Don't put config in metadata
+return PluginResult(
+    haproxy_config="use-fcgi-app fcgi_example",
+    metadata={
+        "fcgi_app_definition": "fcgi-app fcgi_example\n    docroot /var/www"  # Wrong!
+    }
+)
+```
+
+### 3. Error Handling
 
 Always handle errors gracefully to avoid breaking HAProxy configuration.
