Updates for forward compatibility with hsds 1.0 storage
Modify handling of default request (no parameters) so a 200 is returned (rsp is a list of top-level domains)

---

Important

Enhance domain request handling and layout retrieval for forward compatibility with hsds 1.0 storage, including updated tests.

• Behavior:
  • Modify default request handling in domain_sn.py to return 200 with a list of top-level domains when no parameters are provided.
  • Ignore 'db' key at top level in get_domains() in domain_sn.py.
  • Add include_hrefs parameter to get_domains() to include hrefs in domain JSON.
  • Update GET_Domain in domain_sn.py to handle cases where no domain is passed, returning top-level domains.
  • Log warnings for deprecated 'host' parameter usage in GET_Domain.
• Functions:
  • Add _getLayout() and getLayoutClass() in dsetUtil.py and chunkUtil.py to retrieve layout information from dataset JSON.
  • Use getLayoutClass() in datanode_lib.py to replace direct access to layout class.
• Error Handling:
  • Remove error raising for missing layout in chunk_crawl.py and chunkUtil.py.
  • Log and raise HTTP errors in dsetUtil.py when layout information is missing or incorrect.
• Tests:
  • Update testNullDomain in domain_test.py to expect 200 status and validate domain list.
  • Adjust testGetDomain in domain_test.py to check for updated domain response structure.
  • Modify testGet in dataset_test.py to handle changes in layout retrieval logic.

It would eventually be nice to re-organize the utils to avoid having to duplicate helpers like this.
