Enable structured logging for RESTler request sequences

[marina-p]

This change adds structured logging for all of the network traffic that is currently logged to the network.*.txt log. The data is written to a 'trace database'. The default format is newline-delimited json, but custom logging formats are supported via a module specified in the engine settings (similar to checkers).

Below is an example for demo_server:

{"sent_timestamp": "2023-11-02T10:10:59.544824+00:00", "received_timestamp": null, "request": "GET /api/blog/posts?page=1&per_page=1 HTTP/1.1\r\nAccept: application/json\r\nHost: localhost\r\nContent-Length: 0\r\nx-restler-sequence-id: fe2172ab-151c-419f-b918-f3e7483b3230\r\n\r\n", "response": null, "request_json": "null", "response_json": null, "tags": {"request_id": "27f9653431313fdc3fecc4a890b72b80b4ce1e59", "sequence_id": "fe2172ab-151c-419f-b918-f3e7483b3230", "combination_id": "1950cbddab7726489624c3d346d3426561c921ad_1", "hex_definition": "6daf8d22c7a6b3472fc83c9f08f290b3507c3ff3", "origin": "main_driver"}}

{"sent_timestamp": null, "received_timestamp": "2023-11-02T10:10:59.597613+00:00", "request": null, "response": "HTTP/1.1 400 Bad Request\r\ndate: Thu, 02 Nov 2023 10:10:58 GMT\r\nserver: uvicorn\r\ncontent-length: 41\r\ncontent-type: application/json\r\n\r\n{\"detail\":\"per_page must be at least 2.\"}", "request_json": null, "response_json": null, "tags": {"request_id": "27f9653431313fdc3fecc4a890b72b80b4ce1e59", "sequence_id": "fe2172ab-151c-419f-b918-f3e7483b3230", "combination_id": "1950cbddab7726489624c3d346d3426561c921ad_1", "hex_definition": "6daf8d22c7a6b3472fc83c9f08f290b3507c3ff3", "origin": "main_driver"}}

Testing:

• demo_server
• added new unit test
• manual testing for multiple db files
