Add RequestScopedPipeline for safe concurrent inference, tokenizer lock and non-mutating retrieve_timesteps (#12328) * Basic implementation of request scheduling * Basic editing in SD and Flux Pipelines * Small Fix * Fix * Update for more pipelines * Add examples/server-async * Add examples/server-async * Updated RequestScopedPipeline to handle a single tokenizer lock to avoid race conditions * Fix * Fix _TokenizerLockWrapper * Fix _TokenizerLockWrapper * Delete _TokenizerLockWrapper * Fix tokenizer * Update examples/server-async * Fix server-async * Optimizations in examples/server-async * We keep the implementation simple in examples/server-async * Update examples/server-async/README.md * Update examples/server-async/README.md for changes to tokenizer locks and backward-compatible retrieve_timesteps * The changes to the diffusers core have been undone and all logic is being moved to exmaples/server-async * Update examples/server-async/utils/* * Fix BaseAsyncScheduler * Rollback in the core of the diffusers * Update examples/server-async/README.md * Complete rollback of diffusers core files * Simple implementation of an asynchronous server compatible with SD3-3.5 and Flux Pipelines * Update examples/server-async/README.md * Fixed import errors in 'examples/server-async/serverasync.py' * Flux Pipeline Discard * Update examples/server-async/README.md * Apply style fixes --------- Co-authored-by: Sayak Paul <spsayakpaul@gmail.com> Co-authored-by: github-actions[bot] <github-actions[bot]@users.noreply.github.com>
