Proposed commit message

Adds support for Ubiquiti UniFi Activity and Traffic Logging, aka. SIEM integration via syslog/UDP, as well as webhook based event delivery from UniFi systems to an Elastic Agent http_endpoint listener.

Checklist

• I have reviewed tips for building integrations and this pull request is aligned with them.
• I have verified that all data streams collect metrics or logs.
• I have added an entry to my package's changelog.yml file.
• I have verified that Kibana version constraints are current according to guidelines.
• I have verified that any added dashboard complies with Kibana's Dashboard good practices <<< NOTE: this is not publically accessible and requires team based access/authentication, I have instead reviewed https://www.elastic.co/docs/extend/integrations/dashboard-guidelines once again.

Author's Checklist

Please ensure close review of the agent stream templates for the logs data stream.

Significant hackery has had to occur via javascript scripting and if there's a better way of doing this stuff I'd love to hear suggestions.

How to test this PR locally

Sufficient pipeline and system test logs have been provided, review the content and run the tests should suffice.

@colin-stubbs thank you for your contribution - I would suggestion that you tag @elastic/sec-deployment-and-devices as reviewers. I would also suggest that you label the github ownership to that team and mark it as community contributed.
Here's an example of that within the arista_ngfw integration
