Refactors config validation of a service to use a ServiceConfig data object.
Instead of passing around a bunch of related scalars, we can use the
ServiceConfig object as a parameter to most of the service validation functions.
This allows for a fix to the config schema, where the name is a field in the
schema, but not actually in the configuration. My passing the name around as
part of the ServiceConfig object, we don't need to add it to the config options.
Fixes#2299
validate_against_service_schema() is moved from a conditional branch in
ServiceExtendsResolver() to happen as one of the last steps after all
configuration is merged. This schema only contains constraints which only need
to be true at the very end of merging.

This bug can be seen by the change to the test case. When the extended service
uses a different name, the error was reported incorrectly.
By fixing this bug we can simplify self.signature and self.detect_cycles to
always use self.service_name.

ServiceLoader has evolved to be not really all that related to "loading" a
service. It's responsibility is more to do with handling the `extends`
field, which is only part of loading. The class and its primary method
(make_service_dict()) were renamed to better reflect their responsibility.
As part of that change process_container_options() was removed from
make_service_dict() and renamed to process_service(). It contains logic for
handling the non-extends options.
This change allows us to remove the hacks from testcase.py and only call
the functions we need to format a service dict correctly for integration tests.

Consolidates all the top level config handling into `process_config_file` which
is now used for both files and merge sources.

Includes some refactoring of log_printer_test to support checking for flush(), and so that each test calls the unit-under-test directly, instead of through a helper function.

It's a flag passed to docker build that removes the intermediate
containers left behind on fail builds.

Remove some unnecessary newlines.
Remove a unittest that was attempting to test behaviour that was removed a while ago, so isn't testing anything.
Updated some unit tests to use mocks instead of a custom fake.

- make it a positional arg, since it's required
- make it the first argument for all functions that require it
- remove an unnecessary one-line function that was only called in one place

Ensure config_hash is updated when volumes_from mode is changed, and
service is recreated on next up as a result.

Environment keys that contain no value, get populated with values taken
from the environment not from the build phase but from running the command `up`.

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

splitdrive doesn't handle relative paths, so if volume_path contains
a relative path, we handle that differently and manually set drive to ''.

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.
