description:
Added support for HTTPS URLs to the Fetch API.

The fetch API now accepts an extra parameters:
- verify: boolean (default true) to control server certificate
verification.

Verification process can be controlled with the following directives
from the http js and stream js modules:
- js_fetch_ciphers
- js_fetch_protocols
- js_fetch_verify_depth
- js_fetch_trusted_certificate

In collaboration with Dmitry Volyntsev.
