- Add the ability to stick metadata attached to a value in expressions. Currently uses Frame.Meta.Custom.
- None of this is consumed by anything yet, so an incremental step.
This is a translation of services/alerting/conditions. Main Changes:
- Work with types in SSE (series/number) which are data frames (no more null.Float).
- The query part from alerting/conditions is handled by SSE logic
- Convey / simplejson removed.
- Time range no longer part of "query" in the condition
