http: add hmac support for sha256
It seems current hmac implementation use md5 for the hash,
V4 signature require sha256, so I've added the needed struct in
this commit.

I've added the functions that do the hmac in v4 signature file
as a static function ,in the next patch of the serie,
because it's used only by this file.
