Add support for HTTP Upload headers

Browse source 
Some services use Authorization header [0] to pass upload credential
data. This avoids the token being exposed in server logs and is allowed
by XEP-0363 since version 0.5.0.

This change adds support for headers allowed in XEP-0363: Authorization,
Expires and Cookie.
