Create `recording` command for `azpysdk` CLI

We should support test recording management controls in the `azpysdk` CLI instead of continuing to rely on the current `scripts/manage_recordings.py` script. For example:

```python
# Push local test recordings to the assets repo
azpysdk recording push
```

This verb should leverage the existing asset sync tooling and just make it easier to access. Related to https://github.com/Azure/azure-sdk-for-python/issues/44277.
