fix(native-federation-runtime) runtime crash with non-JS routing (like static HTML apps or SSR apps)

[Aukevanoost]

This issue is an edge case:

Since the ‘host remoteEntry.json’ fetch is hardcoded as a relative URL, therefore when used in Stateful SSR websites like (Java Wicket, Ruby, PHP etc.) or static HTML websites. The relative url will fail on all pages that are not the homepage.

Example

With this file structure

/
└── public/
    ├── products/
    │   └── index.html
    ├── contact/
    │   └── index.html
    ├── index.html
    └── remoteEntry.json

RemoteEntry.json resolves on

• https://example.com/

** RemoteEntry.json fails to resolve on**

• https://example.com/products/
• https://example.com/contact/

Solution

Assuming these websites don't have anything to share or expose anyway, an 'opt-out' functionality for the host that prevents the fetch of a potentially useless remoteEntry.json object, combined with a way to provide an url for other edge cases. With as default the hardcoded url to be backwards compatible.
