[opentelemetry-audit] Create first version of Greenhouse Plugin for audit logging

[timojohlo]

Context

This ticket should track the progress for the first version of a audit-logging plugin.

Acceptance Criteria

• Define what kind of logs are required for audit-logging (also check what we already have available in Greenhouse)
• Define standards for our landscape (align with colleagues e.g. here)
• Define architecture: e.g. same as the OpenTelemetry plugin with operator and collectors on each node?
• Define necessary receivers, processors and exporters
• Build first version of Plugin including PluginDefinition with custom fields

Define what kind of logs are required for audit-logging (also check what we already have available in Greenhouse)
Define standards for our landscape (align with colleagues e.g. open-telemetry/community#2409)

These two are being discussed through the WGs and specifications will be implemented once we have a set.

Build first version of Plugin including PluginDefinition with custom fields

The first version will be similar to the already existing OpenTelemetry plugin. As we get audit specific labels/structures this will diverge.
