Is your feature request related to a problem? Please describe.
We use swagger to generate our api client that uses HttpRequest from @angular/common/http. When the request is made from this library the nativescript implementation of the request function runs however I have not been able to find a way to supply nativescript's HttpRequestOptions (timeout) because the angular's module doesn't support it. The default timeout in iOS is 60 seconds and unfortunately I have a use case where I need to extend this amount.

Describe the solution you'd like
A solution for this may be to look for a timeout value supplied in the headers of the request and map it if HttpRequestOptions.timeout is not supplied:

https://github.com/NativeScript/NativeScript/blob/master/packages/core/http/http-request/index.ios.ts#L102

Describe alternatives you've considered
I tried various ways of forcing a timeout option into the angular http request object but it doesn't work.
