[BUG] Rest Requests do not properly parse named wildcards

[dbwiddis]

What is the bug?

A Rest Handler route using a named param does not match.

How can one reproduce the bug?

Add a route which includes a named param. For example

def routes(self) -> list[NamedRoute]:
    return [NamedRoute(method=RestMethod.GET, path="/hello", unique_name="greeting"),
            NamedRoute(method=RestMethod.GET, path="/hello/{name}", unique_name="personal_greeting")]

Then send a Rest Request such as /hello/Tester.

This results in

ERROR:root:'GET /hello/Tester'
Traceback (most recent call last):
  File "/Users/danielwiddis/git/opensearch-sdk-py/samples/hello/hello.py", line 48, in handle_connection
    output = request_handlers.handle(request, input)
  File "/Users/danielwiddis/git/opensearch-sdk-py/src/opensearch_sdk_py/actions/request_handlers.py", line 35, in handle
    return handler.handle(request, input) if handler else None
  File "/Users/danielwiddis/git/opensearch-sdk-py/src/opensearch_sdk_py/actions/internal/extension_rest_request_handler.py", line 31, in handle
    response = ExtensionRestHandlers().handle(route, extension_rest_request)
  File "/Users/danielwiddis/git/opensearch-sdk-py/src/opensearch_sdk_py/rest/extension_rest_handlers.py", line 45, in handle
    return self[route].handle_request(request)
KeyError: 'GET /hello/Tester'

What is the expected behavior?

The Rest Request is sent to the correct handler, and the params map is populated with the named wildcard key and value (in this case, params["name"] = "Tester" and this code would then work:

consumed_params = list[str]()
if rest_request.params["name"]:
    consumed_params.append("name")
    response_bytes = bytes("Hello " + rest_request.params["name"] + "!", "utf-8") + b"\x20\xf0\x9f\x91\x8b"
else:
    response_bytes = bytes("Hello from Python!", "utf-8") + b"\x20\xf0\x9f\x91\x8b"
return ExtensionRestResponse(RestStatus.OK, response_bytes, ExtensionRestResponse.TEXT_CONTENT_TYPE, consumed_params=consumed_params)

Do you have any additional context?

This relates to #35 in that we need to track wildcards in the RestHandlers class and keep track of their original names. Matching incoming strings will be more complex than a dictionary key. I expect glob matching will be the most straightforward solution, or instead of using a regular dictionary use a Trie like OpenSearch's PathTrie
