Is this required for giving the flexibility to custom handler implementations?

In the default implementation of RetryHandler and RedirectHandler, the constructors end up calling the default option constructors if they are null. Default constructors of options are already using these default values. This piece of code seems equivalent to:

Suggested change
final RedirectOptions redirectOptions =
request.getMaxRedirects() == DEFAULT_MAX_REDIRECTS && request.getShouldRedirect().equals(DEFAULT_SHOULD_REDIRECT)
? null
: new RedirectOptions(request.getMaxRedirects(), request.getShouldRedirect());
final RetryOptions retryOptions =
request.getMaxRetries() == DEFAULT_MAX_RETRIES && request.getDelay() == DEFAULT_DELAY && request.getShouldRetry().equals(DEFAULT_SHOULD_RETRY)
? null
: new RetryOptions(request.getShouldRetry(), request.getMaxRetries(), request.getDelay());
final RedirectOptions redirectOptions = new RedirectOptions(request.getMaxRedirects(), request.getShouldRedirect());
final RetryOptions retryOptions = new RetryOptions(request.getShouldRetry(), request.getMaxRetries(), request.getDelay());

Hi @zengin
The changes you are suggesting work effectively the same as the current code of the library. If you take a look at CoreHttpProvider's line 245:

if(redirectOptions != null) {
	corehttpRequestBuilder = corehttpRequestBuilder.tag(RedirectOptions.class, redirectOptions);
}
if(retryOptions != null) {
	corehttpRequestBuilder = corehttpRequestBuilder.tag(RetryOptions.class, retryOptions);
}

RedirectHandler's line 133:

RedirectOptions redirectOptions = request.tag(RedirectOptions.class);
redirectOptions = redirectOptions != null ? redirectOptions : this.mRedirectOptions;

and RetryHandler's line 179:

RetryOptions retryOption = request.tag(RetryOptions.class);
retryOption = retryOption != null ? retryOption : mRetryOption;

you can see that mRedirectOptions and mRetryOption will never be used. Thus it is impossible to customize them so to speak globaly.

Thanks for clarifying.
