Added a source table schema to cat based on the output parquet file. Added the 3 source table pipelines to ci_hsc_gen2, done per ccd for the WriteSourceTable & TransformSourceTable, per visit for ConsolidateSourceTable. The validation includes the simple check of the column names against the cat schema, just like how it's done with the object table.
Yusra AlSayyad may you please review it?
