Prefixes in option names are redundant?

[mgrebenets]

I think prefixing each option name with altool_ is redundant.
It's already clear that these options are for altool action, so instead of

    altool(
        altool_username: ENV["FASTLANE_USER"],
        altool_password: ENV["FASTLANE_PASSWORD"],
        altool_app_type: "ios",
        altool_ipa_path: "./build/Your-ipa.ipa",
        altool_output_format: "xml",
    )

It should rather be:

    altool(
        username: ENV["FASTLANE_USER"],
        password: ENV["FASTLANE_PASSWORD"],
        app_type: "ios",
        ipa_path: "./build/Your-ipa.ipa",
        output_format: "xml",
    )

This will also make this plugin aligned with other Fastlane actions and plugins
