[Libvir] Proposal: Python bindings should turn NO_DOMAIN/NO_NETWORK errors in KeyError exceptions

["Richard W.M. Jones" <rjones redhat com>]

I propose that we should change the Python bindings so that when the 
virterror errors VIR_ERR_NO_DOMAIN and VIR_ERR_NO_NETWORK occur in the 
lookup* functions only, should cause KeyError to be raised.

According to:

http://docs.python.org/lib/module-exceptions.html

"[KeyError is] raised when a mapping (dictionary) key is not found in 
the set of existing keys."

I've already changed the OCaml bindings so that these errors get 
converted into Not_found exception, which is the "natural" exception for 
when something is looked up and not found.

Rich.
