Refactored object{,_container} modules breaking backward compatibility

Previously both modules object and object_container had huge overlaps in
functionality. Both allowed to create and delete containers. One would
not have to pass a object to the object module at all and could use it
to manage containers only. Now the object module has been changed to
manage an object in a container only while the object_container module
is responsible for managing Swift containers only.

With object module it is now also possible to pass data instead of a
filename via module options. The container_access functionality has been
dropped from object module. It has been moved and extended as read_ACL
and write_ACL options in object_container module.

With object_container module it is now also possible to manage the
container access with read_ACL and write_ACL options. Those mirror
earlier container_access option of the object module which has been
removed.
