Representation of a Cloud Spanner Instance.

We can use a `Instance` to:

- `reload` itself
- `create` itself
- `update` itself
- `delete` itself

| **Parameters** ||
|---|---|
| **Name** | **Description** |
| `instance_id` | `str` The ID of the instance. |
| `client` | `https://docs.cloud.google.com/python/docs/reference/spanner/latest/google.cloud.spanner_v1.client.Client` The client that owns the instance. Provides authorization and a project ID. |
| `configuration_name` | `str` Name of the instance configuration defining how the instance will be created. Required for instances which do not yet exist. |
| `node_count` | `int` (Optional) Number of nodes allocated to the instance. |
| `processing_units` | `int` (Optional) The number of processing units allocated to this instance. |
| `display_name` | `str` (Optional) The display name for the instance in the Cloud Console UI. (Must be between 4 and 30 characters.) If this value is not set in the constructor, will fall back to the instance ID. |
| `labels` | `dict (str -> str) or None` (Optional) User-assigned labels for this instance. |
| `experimental_host` | `str` (Deprecated) The instance type and host are now managed by the Client. |
