This is a follow-up of ab054868af. The test was
failing because the Shepherd control socket wasn't ready yet. Restore it but
make sure that the control socket is available first.
* gnu/tests/cuirass.scm ("shepherd socket ready"): New test.
("cuirass running"): Restore it.
Instead of returning multiple services in simple-cuirass-services, rely on the
instantiate-missing-services procedure to instantiate postgresql and
postgresql-role-service-type when missing.
Turn simple-cuirass-services procedure into
simple-cuirass-configuration->specs, that takes a simple-cuirass-configuration
record and returns a Cuirass specification.

* gnu/services/cuirass.scm (%default-cuirass-config): Remove it.
(simple-cuirass-services): Rename it to ...
(simple-cuirass-configuration->specs): ... this procedure.
* gnu/tests/cuirass.scm (cuirass-services): Remove postgresql and
postgresql-role services that are automatically instantiated.
(simple-cuirass-service): New variable.
(%cuirass-simple-test): Adapt it to use simple-cuirass-configuration->specs
instead of simple-cuirass-services.
* doc/guix.texi (Simple Cuirass): Update it.
* gnu/services/cuirass.scm (<build-manifest>,
<simple-cuirass-configuration>): New records.
(build-manifest, build-manifest?, simple-cuirass-configuration,
simple-cuirass-configuration?, simple-cuirass-services): New procedures.
(%default-cuirass-config): New variable.
* gnu/tests/cuirass.scm (%cuirass-simple-test): New variable.
* doc/guix.texi (Continuous Integration): Document it.
Rewrite so that "run-cuirass-test" takes an operating-system argument. This is
functionally equivalent.
* gnu/tests/cuirass.scm (%derivation-file, git-service, cow-service,
%cuirass-specs): New variables.
(cuirass-services): New procedure.
(run-cuirass-test): Add an "operating-system" argument.
(%cuirass-test): Adapt it.
(%cuirass-remote-test): Ditto.
