Add RTQP PI SQL support for default value of function parameter

The current version of PI DAS (RTQP Engine) does not support the definition of default values for table-valued function parameters. This is a rather bleak omission, in my view. For example, the following will fail to create the table-valued function: CREATE FUNCTION [MOMS].[fact].[getInstrumentOperationalDataSummaries] ( @StartTime DateTime, @EndTime DateTime, @TimeStep TimePeriod, @TimeType String = 'MostRecentValue' ) AS SELECT i.* ,s.Value FROM MOMS.dim.InstrumentsBase i CROSS APPLY [MOMS].[fact].[Instrument Base Template_GetSummaries] ( i.ElementID, --Element ID @StartTime, --Start Time @EndTime, --End Time @TimeStep, --Time Step @TimeType --Time Type ) s It should not. It is most reasonable to wish to provide a default value for TimeType in the above example. And T-SQL supports it, just by the way.
