VMware: raise more specific exceptions

In certain cases the exception handling for backend errors
would be handled too broadly. This patch elevates the backend exception
to the application so that it can treat specific errors.

In the application we can now handle the following specific exceptions:
 - FileAlreadyExists - for example when moving a directory to a directory
                       that already exists
 - InvalidProperty - for example when using neutron and opaque networks
                     are not supported
 - AlreadyExists - for example a port group already exists
 - NotAuthenticated - for example the operation is denied as because a
                      session is not established

VMware: prevent race for vmdk deletion

Prevent a race condition for the deletion of a file when there
is more than one process trying to erase the file.

In the application we can now handle the following specific exceptions:

 - FileFault - a file access exception
 - FileLocked - an attempt is made to lock a file that is
                already in use
 - FileNotFound - the specific file does not exist

Add boolean convertor to "create multiple servers" API

"create multiple servers" API contains "return_reservation_id" as an
attribute, and the attribute should be boolean. There are the other
boolean attributes such as "on_shared_storage" of evacuate API, they
can be passed with either boolean or string(e.g. "True"). For the
consistency of whole Nova APIs, this patch adds boolean convertors to
multiple_create API.

Add experimental warning for Cells

When we merged Cells a while back, we noted that the usage was
experimental but haven't had a good channel for communicating the
continued state to the user. Since we're adding warning messages
to virt drivers, this patch adds one for Cells as well, in the
Manager's init method.
