Add additional integration testing around training scripts i.e. dreambooth

[williamberman]

Is your feature request related to a problem? Please describe.
We have some integration tests for testing training scripts. These were added pre-dreambooth, so we could add some more!

Existing tests: https://github.com/huggingface/diffusers/blob/main/examples/test_examples.py
CI Call:

diffusers/.github/workflows/push_tests.yml

Line 145 in 19a0ce4

python -m pytest -n 1 --max-worker-restart=0 --dist=loadfile -s -v --make-reports=examples_torch_cuda examples/

Describe the solution you'd like

• Collect list of example scripts that could use more testing
• Determine common flag combinations worth adding tests for
• How e2e do we want to test? Is it worth doing full training runs and adding to nightly? -> we do cpu tests on merge

Status of tested scripts

• train_dreambooth_flax.py
• train_dreambooth_lora.py
• train_dreambooth.py
• train_text_to_image_flax.py
• train_text_to_image_lora.py
• train_text_to_image.py
• textual_inversion_flax.py
• textual_inversion.py
• train_unconditional.py

Nice! Updated PR description with list of scripts already tested and to note that we don't need full training runs on nightly :)
