Example uses non-existent API

The terminate_instance example

https://github.com/oracle/oci-python-sdk/blob/084eedc79c591eefd8ff4647eb50dbc09684707b/examples/launch_instance_example.py#L417-L425

shows use of an API called terminate_instance_and_wait_for_state which was evidently removed in 2.178.0 (40a0ec43ccb3f8cd92490a69b5f55829cf369acf) in favor of terminate_instance_and_wait_for_work_request (with a different API surface).

There don't seem to be tests in this repo that would cover either terminate_instance_and_wait_for_state or terminate_instance_and_wait_for_work_request.

I do want to note that simply deleting a function that has existed since version 1.3.19 (from 2018) is developer-hostile in my books (and caused a minor production issue for us, but that is honestly on me for not having had suitable tests on our end).

Looking at the source, both terminate_instance_and_wait_for_state and terminate_instance_and_wait_for_work_request call client.terminate_instance(); there is no reason I can see that terminate_instance_and_wait_for_state couldn't coexist (with, if you'd like, a DeprecationWarning).

Start with examples/launch_instance_example.py at lines 417-425 and compare the referenced terminate_instance_and_wait_for_state call with terminate_instance_and_wait_for_work_request and their underlying client. Check the existing source and test layout, since the issue reports no coverage for either API. Done means the example uses a valid API and the relevant termination behavior is covered by tests.
