Built-in Retry Mechanism

[okalil]

This proposal aims to provide a built-in way to enable retries for Router loaders, specially useful for unstable network conditions, providing a better user experience

Proposal

Add a new retry property to the following methods:

fetcher.load("/route", { retry: 3 })
revalidator.revalidate({ retry: 3 })
navigate("/route", { retry: 3 })

The retry property can also be a function:

fetcher.load("/route", { retry: (error, attempts) => isNetworkError(error) ? attempts < 3 : false }

Event if the load fails, if there's a one more attempt to be done, the "state" will continue as "loading". Only after all attempts fail, the ErrorBoundary will be rendered.
