This plugin helps printing all critical events in the console. It is not a replacement
of existing logging in ADK. It rather helps terminal based debugging by showing all logs in the console, and serves as a
simple demo so everyone could develop their own plugins.

This change integrates the plugin system with ADK. PluginManager is attached to the invocation context similar to session/artifact/memory.
It includes integrations with following ADK internal callbacks:
* App callbacks: Integrated in the BaseRunner class, in run_async and run_live
* On Message callbacks: Integrated in the BaseRunner class, triggers on run_async.
* Agent callbacks: Integrated in the BaseAgent class. Leveraging the existing *callback functions
* Model callbacks: Integrating in the base_llm_flow.
* Tool callbacks: Integrated in functions.py, wrapped around the code for agent tool_callbacks
Sample code to use plugins:
```python
# Add plugins to Runner
runner = Runner(
app_name="my-app",
agent=root_agent,
artifact_service=artifact_service,
session_service=session_service,
memory_service=memory_service,
plugins=[
MySamplePlugin(),
LoggingPlugin(),
],
)
```

Plugin is a collection of callbacks (lifecycle hooks), including callbacks for Agent, Tools, Model and App. It helps developers to add customizations and change behaviors of their agent application easily
This is the first change that introduces only the base interfaces based on the doc.
plugins folder is generated with `create_symlink.sh plugins`
