Add registerShutdownHook to AutoConfigurationCustomizer interface

[trask]

Is your feature request related to a problem? Please describe.

I'd like to be able to suppress the SDK's shutdown hook and register my own because of shutdown ordering concerns.

Describe the solution you'd like

Expose the registerShutdownHook on AutoConfigurationCustomizer

Describe alternatives you've considered

Casting the AutoConfigurationCustomizer to a AutoConfiguredOpenTelemetrySdkBuilder and calling registerShutdownHook on that class (which works).

This seems reasonable to me 👍

Hmm - I don't think there was an expected use case for this for the SDK. Registering a shutdown hook or not seems like a concern a framework author wouldn't want to let customization, since they generally control the lifecycle of the SDK. The current customizing is mostly for controlling telemetry behavior in extensions but not lifecycle.

Can anyone think of a framework case where it would be good to be able to customize shutdown downstream? Otherwise does it seem better as a javaagent extension if that is more specific to javaagent distros?

Closing as "wontfix" because sufficient time has passed and there are no additional details.
