[Flux ControlNet] Add img2img and inpaint pipelines #9402
Description
We recently added img2img and inpainting pipelines for Flux thanks to @Gothos contribution.
We also have controlnet support for Flux thanks to @wangqixun.
It'd be nice to have controlnet versions of these pipelines since there's been requests to have them.
Basically, we need to create two new pipelines that add the controlnet support from this pipeline to the corresponding pipellines.
