What does this PR do?

Added codes and documentations for conditioonal DETR model. The conditional DETR files are created by using the "add-new-model-like" feature of CookieCutter, based on DETR codes. All tests are passed. One thing I want to ask is that, I have converted the pretrained weights, how shoud I give these weights to you?

The documentation is not available anymore as the PR was closed or merged.

The CI issue is caused by the fact that you have the following lines in src/transformers/models/auto/feature_extraction_auto.py:

("detr", "DetrFeatureExtractor"),
("detr", "DetrFeatureExtractor"),

=> this should be updated to:

("detr", "DetrFeatureExtractor"),
("conditional_detr", "ConditionalDetrFeatureExtractor"),

Thanks a lot for all your work 🤗 merging!
