Add Tags to the IpConfiguration Datastructure

[gsicilianomsft]

Add Tags value to the IpConfiguration data structure. This will be used to store the NC resource Id.
Also add a function to NetworkInterface to get the primary Ip Configuration from the list of IpConfigurations

@madhanrm I'm not sure about adding Tags to IpConfiguration here. Could you please take a look?

[gsicilianomsft]

The added Tags are being used to store the resourceId/guid assigned to the ipConfiguration within the NetworkController. The guids need to be saved somewhere in Moc to allow update and syncing the ipConfigurations to NC. Guids present in NC that aren't in Moc are deleted for example.

Tags were used here in IpConfiguration because the Tag property was also used in NetworkInterface, and NC uses the same method to update the NetworkInterfaces by storing the NC NIC resourceId in the Tag of Moc's NetworkInterface object.
