validation/aggregating/specimens/qualitative_validations_specimens.sql: removed DDL statements, using the steps at wiki.vegpath.org/Aggregating_validations_refactoring#remove-DDL-statements

validation/aggregating/specimens/qualitative_validations_specimens.sql: parameterize queries by datasource

validation/aggregating/**.sql output queries: use `SET join_collapse_limit = 1;` to match public_validations.rematerialize_out_view()

validation/aggregating/specimens/qualitative_validations_specimens.sql: _specimens_12_distinct_collector_name_collect_num_date_w_count: turn off join_collapse_limit instead of enable_mergejoin/enable_hashjoin, because join_collapse_limit is something that we will eventually want to turn off for all queries, which would avoid this query needing special handling. (on the other hand, enable_mergejoin/enable_hashjoin may be necessary for some queries and we probably won't turn them off for all queries.)
