Use DESCRIP_POINT, ANALOG for e-terraPipeline description strings

The PI Connector for e-terraHabitat HabConnect SAMPLER pulls tag descriptions from the PNTNAM and ALGNAM records. For Oil & Gas e-terraPipeline (a.k.a. ETPL or "LMS") customers, the DESCRIP field on those records are usually left blank, or they have a very generic value. The description for new Pi Tags created by this connector should come from the individual POINT or ANALOG records instead. This information was confirmed by a GE employee as being applicable to all current ETPL/LMS customers. For my company, here are a couple of examples: DESCRIP_ALGNAM = "# - Interface Level - #" DESCRIP_ANALOG = "Cavern 1 - Interface Level - Water (Trend)" DESCRIP_PNTNAM = "# Valve #" DESCRIP_POINT = "Manifold Valve T2" DESCRIP_POINT = "DRA Discharge Valve DD1" Please either: make it possible to configurably request DESCRIP off of ALGNAM vs ANALOG and PNTNAM vs POINT, or preferably, just assume that if we've configured for "DESCRIP" (which only applies to an LMS system) that we want the DESCRIP value from the ANALOG or POINT record. Note - this likely means you don't even need to register for any ALGNAM or PNTNAM data, if DESCRIP is the only thing you're getting from those record types.
