redshift/gammastep: use ini file

Not every option is exposed by redshift/gammastep parameters, for
example gamma options are only exposed in configuration file. So this
PR refactors this module to generate a configuration file and pass it
to the redshift/gammastep using -c parameter.

This is a breaking change since there is no support for some of the
older options like `extraOptions`, but unless you use `extraOptions`
it should work without changes.

* The `services.redshift.extraOptions` and `services.gammastep.extraOptions`
options were removed in favor of <<opt-services.redshift.settings>> and
`services.gammastep.settings`, that are now an attribute set rather
than a string. They also support new features not available before, for
example:

for the available additional options in each program.
