* Initial commit for state tracking
* basic state transition logic and tests
* constructor. test and interface fixup
* use new sig for sch.definitionRoutine()
* test fixup
* make the linter happy
* more minor linting cleanup
- Takes the conditions property from the settings column of an alert from alerts table and turns into an ng alerting condition with the queries and classic condition.
- Has temp API rest endpoint that will take the dashboard conditions json, translate it to SEE queries + classic condition, and execute it (only enabled in dev mode).
- Changes expressions to catch query responses with a non-nil error property
- Adds two new states for an NG instance result (NoData, Error) and updates evaluation to match those states
- Changes the AsDataFrame (for frontend) from Bool to string to represent additional states
- Fix bug in condition model to accept first Operator as empty string.
- In ngalert, adds GetQueryDataRequest, which was part of execute and is still called from there. But this allows me to get the Expression request from a condition to make the "pipeline" can be built.
- Update AsDataFrame for evalresult to be row based so it displays a little better for now
