fog--fog/lib/fog/openstack/storage.rb
Brian D. Burns 56c28d2cb2 [openstack|storage] add #put_dynamic_obj_manifest
Renames the current #put_object_manifest method to better differentiate
this from the new #put_static_obj_manifest method. #put_object_manifest
has been retained for backward compatibility.

# Change the current account while re-using the auth token.

# This is usefull when you have an admin role and you're able
# to HEAD other user accounts, set quotas, list files, etc.
#
# For example:
#
# # List current user account details
# service = Fog::Storage[:openstack]
# service.request :method => 'HEAD'
#
# Would return something like:
#
# Account: AUTH_1234
# Date: Tue, 05 Mar 2013 16:50:52 GMT
# X-Account-Bytes-Used: 0 (0.00 Bytes)
# X-Account-Container-Count: 0
# X-Account-Object-Count: 0
#
# Now let's change the account
#
# service.change_account('AUTH_3333')
# service.request :method => 'HEAD'
#
# Would return something like:
#
# Account: AUTH_3333
# Date: Tue, 05 Mar 2013 16:51:53 GMT
# X-Account-Bytes-Used: 23423433
# X-Account-Container-Count: 2
# X-Account-Object-Count: 10
#
# If we wan't to go back to our original admin account:
#
# service.reset_account_name
