Adding protocol option to the traefik_additional_ports

[iFlyinq]

Description

Add UDP protocol support to traefik_additional_ports

Current Behavior

Currently, the traefik_additional_ports configuration only supports TCP protocol. Even when specifying a protocol in the configuration, the template hardcodes protocol: TCP for all additional ports.

Example of current configuration:

traefik_additional_ports = [
  {name = "syslog", port = 1514, exposedPort = 1514}
]

Desired Behavior

Allow specifying the protocol (TCP/UDP) for additional ports through an optional protocol field. If not specified, it should default to TCP for backward compatibility.

Example of desired configuration:

traefik_additional_ports = [
  {name = "syslog-tcp", port = 1514, exposedPort = 1514, protocol = "TCP"},
  {name = "syslog-udp", port = 1514, exposedPort = 1514, protocol = "UDP"}
]

Use Case

This is particularly important for services that need both TCP and UDP support on the same port, such as:

• Syslog (port 514/1514)
• DNS (port 53)
• OpenVPN (port 1194)
• SNMP (port 161/162)

@iFlyinq Totally, but in the meantime, just use the traefik_values helm config variable in kube.tf.
