services: cuirass: Allow passing extra command line options.

This is so that the options supported by the service configuration don't have
to always be changed. Generally though all options should be explicitly
supported and documented, so this is mostly to facilitate experimentation.

* gnu/services/cuirass.scm (<cuirass-configuration>): Add an extra-options
field.
(cuirass-shepherd-service): Pass the extra options to the shepherd servvices.
* doc/guix.texi (Continuous Integration): Document it.
