Module options should not appear in the client bundle

[vloss3]

Motivation / Goals

Module options(incl. defaults set by the module) appear in the Nuxt window object as part of the runtimeConfig, which increases the size of the bundle.

Requirements

Reduce the module options being sent to only what's necessary.

• we want to have module settings in runtimeconfig to simplify code logic
• what is private or public depends on whether it should be hydrated because it is needed on the client.

    drupalBaseUrl: '',   // -> needed at client
    ceApiEndpoint: '/ce-api',   // -> needed at client
    menuEndpoint: 'api/menu_items/$$$NAME$$$', // -> needed at client
    customErrorPages: false, // -> needed at client
    fetchOptions: {  // -> needed at client
    fetchProxyHeaders: ['cookie'], // -> not needed
    useLocalizedMenuEndpoint: true, // -> needed at client
    addRequestFormat: false, // -> needed at client
    exposeAPIRouteRules: true, // -> not needed
    passThroughHeaders: // -> not needed

exposeAPIRouteRules: true, // -> not needed
passThroughHeaders: // -> not needed

seem to be still passed to the client
