* Split the run_hp_search by backend

* Unused import

* Introduce HPO checkpointing for PBT

* Moved checkpoint saving

* Fixed checkpoint subdir pass

* Fixed style

* Enable/disable checkpointing, check conditions for various tune schedulers incl. PBT

* Adjust number of GPUs to number of jobs

* Avoid mode pickling in ray

* Move hp search to integrations

* Only access loss tensor every logging_steps

* tensor.item() was being called every step. This must not be done
for XLA:TPU tensors as it's terrible for performance causing TPU<>CPU
communication at each step. On RoBERTa MLM for example, it reduces step
time by 30%, should be larger for smaller step time models/tasks.
* Train batch size was not correct in case a user uses the
`per_gpu_train_batch_size` flag
* Avg reduce loss accross eval shards

* Fix style (#6803)

* t5 model should make decoder_attention_mask (#6800)

* [s2s] Test hub configs in self-scheduled CI (#6809)

* [s2s] round runtime in run_eval (#6798)

* Pegasus finetune script: add --adafactor (#6811)

* [bart] rename self-attention -> attention (#6708)

* [tests] fix typos in inputs (#6818)

* Fixed open in colab link (#6825)

* Add model card for singbert lite. Update widget for singbert and singbert-large. (#6827)

* BR_BERTo model card (#6793)

* clearly indicate shuffle=False (#6312)

* Clarify shuffle

* clarify shuffle
