Avoid non-posix environment variables

[badtst]

Description

The option to replace the _ in configuration fields with - (kebab-case ?) for environment variables was a bad idea because it creates non-posix environment variables, which should only be composed of numbers, uppercase letters and underscores.

This could create issues in the future when working with some shells and already happened during testing while working withmake.

Instead of using __ as a field delimiter for the environment variables and keep the _ in filed names, we can choose to instead simply remove the _ in the fields (thus moving them from snake_case to nocase ?). It might be less visible but more compact.

Example:

Field name: qpu.tls_verify -> WARDEN_QPU_TLSVERIFY

CHANGED

• Fields of the configuration now automatically nocase aliases instead of kebab-case aliases
