This adds the ability to put arbitrary user metadata during blob creation for
Amazon S3, Rackspace Cloudfiles and Microsoft Azure.
As previously mentioned, this doesn't include the ability to update/delete
individual metadata (but planned for later - this patch is to be committed as a
baseline). The main issue is with S3. Whilst Cloudfiles and Azure provide api calls
for updating and deleting metadata after a blob is created, for S3 it is only
possible to do so when creating the blob. Apparently, S3 clients such as cloudberry
explorer which allow you to update metadata actually *make a copy of the object
with the new metadata* (!)

Another issue which is not yet settled and for which I'd be grateful for
feedback is in server.rb I am using params to get the key-value pairs for the
metadata (submitted by a html form). An alternative, and the way the providers
do it is with custom request headers (X-AMZ-META-KEY = VALUE for S3,
X-OBJECT-META-KEY = VALUE for rackspace etc). This needs some more thought,
