Logging exp

[GRuggieriTES]

This Example PR showcases logging on PHP controllers, using the already used monolog logging library in classcharts, which has been tried and tested there. it is primarily for http at this stage, but also includes UDP for evaluation.
logging comms include

1. A test mock server (node.js) to intercept and listens logs via HTTP and returned to the PHP client, also console logs are shown in the terminal to confirm reception of the logs.
2. The above server also includes a server for syslog comms via UDP
3. A Graylog dashboard in conjunction with elastic search to record the UDP data

i added it here in this example project, so that it can be shared with the team early due to write access restrictions in said project.
