* Prometheus: disable dynamic label lookup on big datasources
- when a prometheus datasource has more than 10000 metrics, label lookup
for the query field is disabled
- installations of that size have slow typehead lookup times and make
the editor sluggish
* Raise dynamic lookup threshold to 10000 metrics
* Run start tasks again
* Chore: Move and wrap Cascader component to @grafana/ui
Closes#19042
* Removes unneeded props from interface and removes rc-trigger
* Removes more unneeded props
As discussed in a UX feedback session, it's annoying that queries are
automatically executed in Explore. This change adds props to override
the blur behavior.
- add `onBlur` to Explore query field props
- Explore's query row will pass down an empty function for onBlur to the
query fields
- pass onBlur through to the QueryField component for Loki and
Prometheus
- add test to QueryField to make sure if onBlur is specified, the
onRunQuery is not executed
* Explore: Remove datasource testing on selector
- datasource testing gets in the way of fast query iteration: switching
between datasources can take seconds
- it should not be explore's duty to test datasources in the first place
- removed the concept of datasourceError in Explore, should not be its
concern
- datasource erorrs will express themselves in query errors just fine
- connection errors are still bubbled up
- removed reconnection logic from explore, should not be its concern
- missing labels in loki are still "visible" via an empty label selector
- Loki and Prometheus treated connection errors differently than other
datasources, making sure to pass through the original error message
* Show datasource error in query field for prom/loki/influx
* Removed connection test case, fixed disabled state
* Fix redirect but adding getExploreState method to graphite
* Explore: Create interpolateVariablesInQueries function for datasources
* Explore: Add interpolateVariablesInQueries method to elasticsearch datasource
* Add interpolateVariablesInQueries function to influx and postgres
* Explore: Add interpolateVariablesInQueries to Mssql and Mysql datasources
* Explore: Add datasources to queries
* Explore: Code formatting
* Prettier formating fix
* Explore: Add rawQuery expanding of variables for influxdb
* Remove console.logs
* Explore: Add rawQuery expanding of multiple variables for influxdb
* Explore: If no queries in Influxdb, return early []
* Explore: Refactor influxDb to follow the code structure
* Loki: Updated cheat sheet with new filter syntax
- updated cheat sheet with new filter syntax
- added user-specific examples from the user's label set
- added link to LogQL docs
- separated styles for examples (clickable) and expressions
