LinuxServer Changes:
Existing users should update: nginx.conf, ssl.conf, proxy.conf, and the default site-conf - Rework nginx.conf to be inline with alpine upstream and relocate lines from other files. Use linuxserver.io wheel index for pip packages. Switch to using ffdhe4096 for dhparams.pem per RFC7919. Added worker_processes.conf, which sets the number of nginx workers, and resolver.conf, which sets the dns resolver. Both conf files are auto-generated only on first start and can be user modified later.
PIP Changes:
Updating PIP version of certbot to 1.15.0
