Use FQDN in Admin->Server for display and regex match

[ckt114]

Summary

Please see attached image for understanding of the request.

Requesting a feature to use FQDN instead of just the hostname when detecting nearby server. Currently it's only using hostname. There is no way to prefix a hostname in docker compose and scale the service and easily use regex in Cronicle to group servers int groups. Docker compose has the domainname key that can be attached.

Steps to reproduce the problem

Run Cronicle in containers

Your Setup

Docker compose
1 master
1 backup
4 slaves (each with random hostname)

Operating system and version?

CentOS 7 running docker 18.09.3

Node.js version?

v10.15.1

Cronicle software version?

0.8.28

Are you using a multi-server setup, or just a single server?

Multi servers

Are you using the filesystem as back-end storage, or S3/Couchbase?

File system

Thanks for the great work.
