Feature Request: Allow setting custom NTP servers

[TheGroundZero]

I prefer to keep IoT devices on a non-internet VLAN where possible.
I also run my own NTP server on the local network and communicate its address via DHCP to clients.

It would be nice to be able to configure my own NTP server either in the Settings page or have the device follow the DHCP options for NTP servers.

I'm working on this in a fork, but I'm not used to working with ArduinoIDE.
So I'm looking to incorporate this: https:/ropg/ezTime#setserver-and-setinterval

[TheGroundZero]

Can anyone try to compile this and check if it works?

@TheGroundZero it was a great first attempt. It almost work at first. I made some changes in your fork I would like to push the changes, I think you have to PR first

@jnthas I've initiated the PR and marked it as editable by the maintainer
