[endlessh] Add endlessh-go compatbility to parser

[Swiiney]

Current endlessh collection uses endlessh C implementation which isn't maintained since 4 years. A new implementation in go is available https://github.com/shizunge/endlessh-go actively developped. The log is sligthly different and the parser should be adapted. The docker implementation encourages to log to docker and not to a file. Acquisition document should be adapted too.

Thanks
