If we get back an error that wasn't an APIError, it was causing the
thread to hang. This catch all, while I appreciate feels risky to
have a catch all, is better than not catching and silently failing,
with a never ending thread.
If something worse than an APIError has gone wrong, we want to stop
the incredible journey of what we're doing.

In order to validate a service name that has been specified as an
integer we need to run that as a pre-process validation step
*before* we pass the config to be validated against the schema.
It is not possible to validate it *in* the schema, it causes a
type error. Even though a number is a valid service name, it
must be a cast as a string within the yaml to avoid type error.
Taken this opportunity to move the code design in a direction
towards:
1. pre-process
2. validate
3. construct

We use $ref in the schema to allow us to specify multiple type, eg
command, it can be a string or a list of strings.
It required some extra parsing to retrieve a helpful type to display
in our error message rather than 'string or string'. Which while
correct, is not helpful. We value helpful.

When a schema type is set as unique, we should display the validation
error to indicate that non-unique values have been provided for a key.
Signed-off-by: Mazz Mosley <mazz@houseofmnowster.com>
The validation message was confusing by displaying only 1 level of
property of the service, even if the error was another level down.
Eg. if the 'files' property of 'extends' was the incorrect format,
it was displaying 'an invalid value for 'extends'', rather than
correctly retrieving 'files'.
Signed-off-by: Mazz Mosley <mazz@houseofmnowster.com>
Unfortunately the way that jsonschema is calling %r on its property
and then encoding the complete message means I've had to do this
manual way of removing the literal string prefix, u'.
eg:
key = 'extends'
message = "Invalid value for %r" % key
error.message = message.encode("utf-8")"
results in:
"Invalid value for u'extends'"
Performing a replace to strip out the extra "u'", does not change the
encoding of the string, it is at this point the character u followed
by a '.

* Add support for volume_driver parameter in compose yml
* Don't expand volume host paths if a volume_driver is specified

When an image declares a volume such as `/var/lib/mysql`, and a Compose
file has a line like `./data:/var/lib/mysql/` (note the trailing slash),
Compose creates duplicate volume binds when *recreating* the container.

Hard-coding the API version to '1.18' with the docker-py constructor will
cause the docker-py logic at
https://github.com/docker/docker-py/blob/master/docker/client.py#L143-L146
to always fail, which will cause authentication issues if you're using a
remote daemon using API version 1.19 - regardless of the API version of
the registry.
Allow the user to set the API version via an environment variable. If
the variable is not present, it will still default to '1.18' like it

Sometimes, some messages were being executed at the same time, meaning
that the status wasn't being overwritten, it was displaying on a

A circular reference bug occurs when there is a difference in the paths
of the file specified in the extends. So one time it is relative, second
time is absolute thus allowing a further circular reference to occur.

This refactoring allows us to raise an error when there is no
