This PR adds ability to set schedulers using a json string in the request for t2i and i2i pipeline.
nameof the scheduler can be a preset or a class name for the scheduler fromdiffusers.There are presets to make setting the main schedulers easier from https://huggingface.co/docs/diffusers/en/api/schedulers/overview.
Scheduler is created by mapping the preset name to the
diffusersscheduler class usingimportlibso the schedulers are not imported until needed.If a scheduler fails to be added the pipeline raises an error. If no scheduler is specified the default scheduler is applied.
