Add HP iLO integration

[CallumDowling]

Integration release checklist

HP iLO is an embedded server management system which works via ethernet and is installed on most HP Prolient servers. It allows for publishing remote syslog messages, hence this integration request.

This is an important data source for a SOC as it would support intrusion detection/prevention for auth requests as well as analytics for the various heartbeat logs it sends.

A working custom log ingest configuration, ingest pipeline and a dashboard for HP iLO has been created, A pull request will be created referencing this issue shortly.
