External volumes are created and managed by the user.
They are not namespaced.
They are expected to exist at the beginning of the up phase.

Assume version=1 if file is empty in get_config_version
Empty files are invalid anyway, so this simplifies the algorithm
somewhat.

* Bump default API version to 1.21 (required for named volume management)
* Introduce new, versioned compose file format while maintaining support
for current (legacy) format
* Test updates to reflect changes made to the internal API

We were essentially only testing that *at least one* of the invalid
values fails the validation check, rather than that *all* of them fail.

Split env resolving into two phases. The first phase is to expand the paths
of env_files, which is done before merging extends. Once all files are merged
together, the final phase is to read the env_files and use them as the base
for environment variables.

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.

- 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
