Make DH parameters optional

[thtomate]

They are not needed anymore and it even gives a warning if you have them.

Hi @thtomate can you give some more information about this?

• Which parameters should be changed to be optional? Puppet or freeradius configuration?
• What is the warning message that is given?
• Is this a freeradius change and freeradius warning, or, something in puppet?

[thtomate]

The freeradius parameter dh_file in eap module config.

Warning on freeradius start-up:

Wed Apr 12 20:40:04 2023 : Warning: tls: Setting DH parameters from /etc/freeradius/certs/dh - this is no longer necessary.
Wed Apr 12 20:40:04 2023 : Warning: tls: You should comment out the 'dh_file' configuration item.

I understand the issue now @thtomate - let's resolve this as part of #184
