[ASTERIXDB-3117][EXT] Allow specifying a subpath for EXTERNAL datasets queries

- user model changes: no
- storage format changes: no
- interface changes: yes

Details:
This patch is to allow users to specify a subpath in queries scanning
external data sources like S3.

- add "subpath" hint to allow specifying a subpath to be used in
  conjunction with the "definition" of external datasets.
- capture the "subpath" hint for each term in the FROM clause.
- pass the hint to the properties of IDataSource and expose them.
- Op Isomorphism: compare IDataSource properties only for EXTERNAL datasets.
