This change adds cgroup-parent support to compose project. It allows
each service to specify a 'cgroup_parent' option.

Including examples of more boolean types, eg yes/N as it's not
always immediately clear that they are treated as booleans.

Rather than inefficiently looping through all the containers that a
service has and overriding each volumes_from value, pick the first
one and return that.

An expanded windows path of c:\shiny\thing:\shiny:rw
needs to be changed to be linux style path, including the drive,
like /c/shiny/thing /shiny
to be mounted successfully by the engine.

When a relative path is expanded and we're on a windows platform,
it expands to include the drive, eg C:\ , which was causing a ConfigError
as we split on ":" in parse_volume_spec and that was giving too many parts.
Use os.path.splitdrive instead of manually calculating the drive.
This should help us deal with windows drives as part of the volume
path better than us doing it manually.

This is a breaking change. The deprecation warning preparing users for
this change has been removed.

It was mocking self.client but relying on the call to
utils.create_host_config which was not mocked. So now that function
has moved to also be on self.client we need to redefine the test
boundary, up to where we would call docker-py, not the result of
docker-py.

This is a unit test and we are mocking the client. The method to get
the create_config_host now lives on the client, so we mock that too.
So we can test to the boundary that the method is called with the
arguments we expect.

One of the use cases is swarm requires at least : character, so going

We're going to warn people that allowing a boolean in the environment is
being deprecated, so in a future release we can disallow it. This is to
ensure boolean variables are quoted in strings to ensure they don't get
mis-parsed by YML.
Signed-off-by: Mazz Mosley <mazz@houseofmnowster.com>
When users were putting true/false/yes/no in the environment key,
the YML parser was converting them into True/False, rather than leaving
them as a string.
This change will force people to put them in quotes, thus ensuring
that the value gets passed through as intended.

English language is a tricky old thing and I've pulled out the validator type
parsing so that we can prefix our validator types with the correct article,
'an' or 'a'.
Doing a bit of extra hard work to ensure the error message is clear and

We want to give feedback to the user as soon as possible about the
validity of the config supplied for the services.
When extending a service, we can validate that the fields are
correct against our schema but we must wait until the *end* of
the extends cycle once all of the extended dicts have been merged
into the service dict, to perform the final validation check on the
config to ensure it is a complete valid service.
Doing this before that had happened resulted in false reports of
invalid config, as common config when split out, by itself, is not
a valid service but *is* valid config to be included.

This refactoring is now really coming together. Construction is
happening in the __init__, which is a constructor and helps
clean up the design and clarity of intent of the code. We can now
see (nearly) everything that is being constructed when a ServiceLoader
is created. It needs all of these data constructs to perform the
domain logic and actions. Which are now clearer to see and moving
more towards the principle of functions doing (mostly)one thing and
function names being more descriptive.
resolve_extends is now concerned with the resolving of extends, rather
than the construction, validation, pre processing and *then* resolving
of extends.
Happy days :)

Moving service name and dict out of the function make_service_dict
and into __init__. We always call make_service_dict with those so
let's put them in the initialiser. Slightly cleaner design intent.
The whole purpose of the ServiceLoader is to take a
service name&service dictionary then validate, process and return
service dictionaries ready to be created.
This is also another step towards cleaning the code up so we can
interpolate and validate an extended dictionary.
