Adds ability to run as daemonset or deployment with hostNetwork set

[meik99]

Goal

• Add option to deploy a daemonset instead of a deployment
• Add option to set hostNetwork to true

Context

When running in a cluster with multiple nodes and load balancing, it can be necessary to run coturn as a daemonset so each target node has the ability to function correctly.

Additionally, the hostNetworking option simplifies configuration of other services, since default low-ports can be used and don't have to be mapped to the high ports exposed by NodePorts.

For my specific use case, TCPRoutes and UDPRoutes are currently not yet available with the Gateway implementation I am using (Cilium) so this deployment option can simplify configuration for others in the same scenario

Tests

• Ran helm template . with
  • deployment type set to both values
  • deployment being set to nil
• DaemonSet currently live in my home lab
