Reading the entire tar file into memory can result in out-of-memory
conditions such as this traceback:

msg += message_body
MemoryError
Luckily docker-py's load_image(), which calls requests post(), accepts a
file-like object instead of a string. Pass in the file object to avoid
reading the full file into memory. This allows larger tar files to load
succesfully.

* This moves the lines in the code that parse the `env` and `env_file` options for docker to the end of the `__init__()` function.
This is needed because the `_check_capabilites` function needs both a working `self.client` and a proper `self.docker_py_versioninfo`.
`_check_capabilities` is used by `ensure_capabilities` which is, in turn, used by `get_environment`
This means that before this commit, the environment variables could not be loaded because both `self.client` and `self.docker_py_versioninfo` were not set at that time.
This commit fixes that by putting the environment variable parsing after those two.
