Change casing style for gateway config options to use elixir styling not gateway style.

[pkrawat1]

Currently, we are using the gateway expected case styling in the gateway config block in the application code.

This introduces a lot of disparity in between the gateway configs.

Proposal:-

We have a common style and we create a map at gateway level in library to interface gateway keys with config application level keys.

Changes to be made in all the existing gateways;

• Map all the application level config keys to the gateway specific keys and then send the request.
• any other changes?.. developing...

This would ensure that we have a consistent API for config.

I'm sorry I don't understand the issue. Could you link to the offending code to make this clear?
What is "case styling"? snake_case vs CamelCase?
The Elixir Naming Conventions do allow CamelCase atoms, though not in (core) Elixir.
