Added the 'Optional' extra require in setup.py (open-mmlab#1491)

* Added the 'Optional' extra require in setup.py

Added the missing extra of "optional" as seen in other MM repos as mmaction2  (https://github.com/open-mmlab/mmaction2/blob/master/setup.py#L193)   and mmdetection  (https://github.com/open-mmlab/mmdetection/blob/master/setup.py#L216)

Without it, users who are used to install mmlab packages will automatically add the "optional" extra and will encounter a pip error

* move albumentations from optional.txt to albu.txt

* addd pip install albumentations command in the workflow
