Custom convoTitle timeout

[rakovskij-stanislav]

Currently, there is a strict deadline for title generation - 45 seconds (

LibreChat/api/server/services/Endpoints/agents/title.js

Line 76 in f10b1d9

timeoutId = setTimeout(() => reject(new Error('Title generation timeout')), 45000);

)

I suggest to make it customizable (for instance, if you are self-hosted or have a large conversation that cannot be titled with this deadline).

According to Contributing guildelines, I raise this discussion.

I implemented the draft the title convo timeout: https://github.com/rakovskij-stanislav/LibreChat/tree/feat/add-convo-title-deadline

1. 45 seconds as default.
2. User can redefine them in env by setting TITLE_CONVO_TIMEOUT_MS.
3. User can specify convo timeout for each provider in librechat.yaml by using path endpoints.<endpoint name or "all">.titleTimeoutMs - it has more priority than env.
