Ali Beyad 4431720c3d File-based discovery plugin (#20394) ... This commit introduces a new plugin for file-based unicast hosts discovery. This allows specifying the unicast hosts participating in discovery through a `unicast_hosts.txt` file located in the `config/discovery-file` directory. The plugin will use the hosts specified in this file as the set of hosts to ping during discovery. The format of the `unicast_hosts.txt` file is to have one host/port entry per line. The hosts file is read and parsed every time discovery makes ping requests, thus a new version of the file that is published to the config directory will automatically be picked up.
