Update documetation (canonical#314)

1. containers.rst: Add a newline to ensure syntax of admonition will take effect.
2. image.rst:
  a) The default value of wait argument in create() is True. (refs image.py#L101)
  b) The first argument in create() is the binary data of the image. Therefore, image_data should be opened in 'rb' mode. Or you will get an error.
3. operations.rst: Correct typo.
