investigate the use of logic constructs and labels with respect to endpoint identification

[djhaynes]

During the 3/9/16 SACM Virtual Interim Meeting, it was suggested that it may be good to have logic constructs (e.g. at least one, etc.) and labels to eliminate the need to carry endpoint identification attributes along with posture attributes every time they are exchanged between SACM Components.

This should be supported via the "target endpoint label" as defined in the Terminology I-D. Furthermore, it will be supported in the IM with the addition of the te-label IE that is defined I-D IM (https://github.com/henkbirkholz/sacmim/blob/master/draft-camwinget-sacm-information-model-01.md) and has yet to be converted over to the IPFIX syntax and included in the WG IM.

I am going to close out this tracker for now given the target endpoint label. Let me know if there are any strong objections to this and I will reopen it.
