Users have asked for this multiple times, so I decided to make a PR for it.
This is tested locally
Tests made:
change config, refresh page, check for the persistence of config
test embedding, if semaphore value is applied correctly (worked perfectly)
defaults to zero which means unlimited (old existing behaviour)
only displays in the UI, if async embedding is on at all
tested OpenAI embedding with 0, 1, 5 and 10 set as the value - speed adjusted accordingly, worked perfectly.
values persisted
