Title: support for bucket.head() metadata request

this implements a bucket.head() method that retrieves only metadata for a existing key using HTTP HEAD /... instead of HTTP GET /...
The rationale behind is that this is much more lightweight method if one wants to check if a key exists or wants to retrieve a vclock for updating, especially with bigger contents
