lmishell, instance filtering

[Peter Hatina]

Hi,

from now, there is a preferred way, how to filter instances and instance
names by using a dictionary. The old means of filtering still works, as
well.

Examples (with networking provider):

eth0 = cimv2.LMI_IPNetworkConnection.first_instance(key="Name",
value="eth0")

vs.

eth0 = cimv2.LMI_IPNetworkConnection.first_instance({"Name" : "eth0"})

The main reason, why we switched to this is: there can be more filter
elements present:

active_ifs = cimv2.LMI_IPNetworkConnection.instances({"EnabledDefault" :
2, "OperatingStatus" : 16})

Cheers

Do we need to use the magic numbers, or can we use something like
"OperatingStatus" : on ?

That's a major piece of usability. In the python-world, we probably
want this to be represented by something like an enum:

OperatingStatus.ON
OperatingStatus.OFF

etc.

It is on a todo list in the track (fedorahosted.org).

This ticket specifically mentions JobStatus values; will the
implementation support every case where magic numbers are used, or is
the implementation on a function by function basis?
