Customize HttpClientHandler

[ddydeveloper]

Goog morning!

I've investigate in short the github code just to be familiar with it. Unfortunately, I didn't find any options to custimize HttpClientHandler. It can be useful in this way:

1. I am getting security error after google API request. The reason is experid certificate, e.g.;
2. I can't be sure, so the next way to override ServerCertificateCustomValidationCallback;
3. If it works after overriding - the reason is an expired certificate.

What do you think, is it goog idea to provide such stuff for the customization or not? At least the logs can be extended to clearly understand the problem, right now I can see just:

A security error occurred
