Some dbt_utils.get_relations_by_* macros

[jtcohen6]

Yes:

• dbt_utils.get_relations_by_prefix (no support for schema patterns), plus get_tables_by_prefix as alias/passthrough
• dbt_utils.get_relations_by_pattern (no support for schema patterns), plus get_tables_by_pattern as alias/passthrough

Both are effectively:

show table extended in {{ schema_pattern }} like '{{ table_pattern }}' / '{{ table_prefix }}*'

It needs to be extended in order to derive relation type (view or table).

No:

• dbt_utils.get_relations_by_prefix_sql
• dbt_utils.get_relations_by_pattern_sql

This is enough to get us Spark/Databricks compatibility for the codegen package, which uses dbt_utils.get_relations_by_prefix here.
