Stop TLS sockets being closed when attaching

Signed-off-by: Ben Firshman <ben@firshman.co.uk>

When calling attach_socket, the response is garbage collected,
which triggers a close method on the file object, closing the socket.
This stop the response from being garbage collected until we've
finished with the underlying socket.

Fixes #350

Restart Policy for Containers Implemented fixes #302

Closes #282

Volumes parameter on create_container should be validated as string

Stop timeout should be added to the request timeout

Using the max of the stop timeout and request timeout did not entirely
make sure that a stop timeout greater than a request timeout wouldn't
fail prematurely with a HTTPTimeout exception. The correct behavior is
to add the timeouts together, as the stop timeout is understood to be
part of the "request processing time". Any transport-level timeout thus
comes in addition to that.
