Summarize your change. This adds the ability to use loki as the backend for frame logs in rqd. It also adds a new plugin/widget in cuegui to read the logs from the loki server.

This enables logs files to not be bound by a single namespace and also adds the potential to also store telemetry about the frame.

This is still on an experimental stage and any inputs are appreciated. Screenshot of new widget :

This also includes #1594 Missing :

• [ ] Search log
• [ ] Documentation on configuring Loki (query range limits)
• [ ] Timestamp in log view
