services: guix-publish: Allow for multi-compression.
This is a followup to b8fa86adfc01205f1d942af8cb57515eb3726c52. * guix/deprecation.scm (warn-about-deprecation): Make public. * gnu/services/base.scm (<guix-publish-configuration>)[compression]: New field. [compression-level]: Default to #f. Add '%' to getter name. (guix-publish-configuration-compression-level): Define as deprecated. (default-compression): New procedure. (guix-publish-shepherd-service)[config->compression-options]: New procedure. Use 'match-record' instead of 'match'. * doc/guix.texi (Base Services): Remove 'compression-level' and document 'compression'.
