[PATCH] Smi-s ping tool

[Tony Asleson]

Basic tool to connect to a provider and check to make sure we can
enumerate instances of CIM_ComputerSystem so we hopefully have
something to test.

+# 1 if we can talk to provider, but no systems
+# 2 Wrong credentials (Wrong username or password)
+# 3 Unable to lookup RegisteredName in registered profile (interop support)

These line got PEP8 warnings:

./smisping.py:29:29: E126 continuation line over-indented for
hanging indent
./smisping.py:30:29: E126 continuation line over-indented for
hanging indent

Amended and pushed.

Thanks.
