Delete Opensearch resources on store deletion

[tombojer]

Improvement

After the deletion of the store resources, the opensearch resources (indices, aliases, ...) still exist.

Unlike the database, the data is ephemeral and can be deleted. To allow an easier automation of the shop lifecycle, the operator should delete the opensearch resources if needed.

Reason

Easier automation and lifecycle management

Information

Via a custom field in the the store crd, the opensearch cleanup should be toggleable.
If activated, the finalizer should stay on the store cr until the opensearch resources are cleaned up.

The required permissions to authenticate against opensearch are stored in the store secret.
