(PXP-6604) DRS endpoint to resolve regardless of prefix

[olivarity]

Jira Ticket: PXP-6604

Now when attempting to GET a record for a specified GUID, the following resolution steps will be taken:

1. Start by trying to resolve the provided ID
2. If unsuccessful, check what the DEFAULT_PREFIX Indexd config is set to
3. If the ID starts with the prefix, attempt to remove the prefix from the provided ID and try resolving again
4. If the ID does not start with the prefix, attempt to add the prefix to the provided ID and try resolving again

New Features

• Added new get_with_nonstrict_prefix helper to index_driver.
• Updated /ga4gh/drs/v1/objects/<path:object_id> and /index/<path:object_id> GET endpoints to utilize this new method.

could you move the non-bullet points part of the PR description to before "New Features"? 🙏 our script that parses PR descriptions to generate release notes interprets each new line as a "new feature"
