Oleksiy Syvokon a8fafdd7ee Pass routing headers to ChatGPT subscription API (#62556)
## Objective

Improve cache hit rate of LLM requests sent to ChatGPT subscription API.

## Solution

Set headers that help route request to the correct servers. This is
ChatGPT specific; plain OpenAI API doesn't require it.

## Testing

I run a benchmark which imitates a thread that makes 20 sequential tool
calls. I tried different cache route strategies. Results are below:


| Configuration                                   | Hit rate |
|-------------------------------------------------|---------:|
| No identity headers, no cache key               | 22.2%    |
| `thread-id` only, no cache key                  | 44.4%    |
| `thread-id` + matching cache key                | 42.1%    |
| Cache key only                                  | 53.6%    |
| Turn state + cache key                          | 47.4%    |
| `session-id` + matching cache key               | 100.0%   |
| `session-id` + `thread-id` + matching cache key | 97.4%    |

Licensing

Zed source code is licensed primarily under GPL-3.0-or-later, with Apache-2.0 components where marked.

License information for third party dependencies must be correctly provided for CI to pass.

We use cargo-about to automatically comply with open source licenses. If CI is failing, check the following:

  • Is it showing a no license specified error for a crate you've created? If so, add publish = false under [package] in your crate's Cargo.toml.
  • Is the error failed to satisfy license requirements for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the accepted array in script/licenses/zed-licenses.toml.
  • Is cargo-about unable to find the license for a dependency? If so, add a clarification field at the end of script/licenses/zed-licenses.toml, as specified in the cargo-about book.
