Allow configuring amplitude event naming convention

Trevin_Chow @Trevin_Chow: Amplitude has settings for enforcing naming conventions. It would be good for Feathery to support full integration by allowing this customization as well so we don’t have different event and property name formats. For example for us, we use Title Case. My understanding from Amplitude is that the 3 most common are: Title, Snake and Camel.
