services: nginx: Make service extensible.
* gnu/services/web.scm (<nginx-configuration>)[server-blocks]: New field. (nginx-activation): When CONFIG-FILE is #f, use 'default-nginx-config'. (nginx-shepherd-service): Likewise. (nginx-service-type): Add 'compose' and 'extend' fields. (nginx-service): Change default value of #:server-list to '(), and default value of #:config-file to #f. * doc/guix.texi (Web Services): Document it. Co-authored-by: Ludovic Courtès <ludo@gnu.org>
