OMC - Open Management with CIM Code

removed hard-coded namespace

allowing for configuring OUT various composite device namespaces

sending a 0 TimeoutPeriod value to RequestStateChange meaning that we have no time constraints. Also, this parameter is not 'optional' in the mof, so we were breaking Pegasus implementations by not sending something.

Relaxed the xml schema to not require the service health info

Added processing for polling interval on service. A little more refactoring

Implemented code to analyze the health data for the service and report the health state

removed redundant Capabilities and ElementCapabilities instances and associations that are already provided by the CompositeCapabilities provider

implemented RequestStateChange method on EthernetPort instances and populated state-related props in EthernetPort and DeviceCapabilities for EthernetPort

made a change to work with changes in pywbem trunk

Implement modifyInstance on health data items
