Support Dynamic DNS like in Docker Package

[Fmstrat]

Hi,

I recently built a docker package that uses a config file with dynamic DNS hosts for synchronization:

HUB: https://hub.docker.com/r/nowsci/plex-sync/
SRC: https://github.com/Fmstrat/plex-sync

Could the dynamic host work be implemented directly? Basically I just grab the cert information to pull the CN that should be used for the connection (with curl) and then use that.

I also plan on adding log parsing for tokens in the docker container if you're not planning on doing that.
