Simplify storing strings/bytes in a Storage

[Thomas Güttler]

Docs: ​https://docs.djangoproject.com/en/3.1/topics/files/#storage-objects

path = default_storage.save('path/to/file', ContentFile(b'new content'))

Things would be bit easier, if save() would support strings/bytes directly.

This way a developer needs to type and import less code:

path = default_storage.save('path/to/file', b'new content')

path = default_storage.save('path/to/file', 'new unicode string, encoded automatically with utf-8')

Would you accept a patch to Storage.save()?

Background: I am writing a unittest which mocked away the storage calls to save() will put the data into the mock.

Then I check if the data is the way I want it.

Now it gets complicated again: I need to access the data which is inside ContentFile grrr.

This would be much easier if you could add strings/bytes to the save() directly.
