* Prometheus: user metrics metadata to inform query hints
- no longer analyse datapoints
- either use metrics metadata to determine metrics type or use metric
name suffix
- removed testcases based on datapoints
* Added hint certainty and tests
* Prometheus: Disable suggestions at beginning of value
- fixed comparison operator regex
- no longer suggest anything at beginning of label value
* Detect cursor in front of label values
* Loki: fix filter expression suggestions
- dont suggest term completion items in filter expression
- allow at least one character before suggesting term items
- keep logql expression when switching between Metrics/Logs mode
- show only history by default in completion items
* Clear results when changing mode
- `unless`, `or` and `and` are binary operators
- if they appear in a query the query was broken up so the suggestor
only works on the current term
- this change fixes the splitter logic to make sure those keywords are
not inside a word
* Prometheus data source: Update tooltip for _Scrape interval_
The old tool tip was plainly wrong. The globally configured scrape
interval is not necessarily the most used scrape interval, so the new
wording is describing what actually matters. The evaluation interval
wasn't even mentioned before. And finally, the configured value is
not strictly a lower limit for the step query parameter as it can be
overridden by the panel option _Min time interval_.
I plan to explain the overriding intricacies in the tool tip for _Min
time interval_.

* Improve tooltip for _Min step_
The previous tool tip was mostly addressing aspects that are not
specific to _Min step_ (and might be more appropriate to be added to
the _Min time interval_ tool tip as that setting has a wider
scope). The new version emphasizes the important gotchas: that this is
an _additional_ lower limit, and that it is _not_ multiplied by the
resolution factor.

Closes#19598
Fixes bug introduced recently where the new PromQueryEditor did not preserve
the PromContext.Explore set on the query model by PromQueryField which caused
the table to be empty for Prometheus in explore.
Much easier to wrap one's head around it if it is expressed more
directly.
This is not mathematically the same as the previous version involved
more rounding than necessary because of the way the intervalFactor was
handled. I'd argue the new version is better because it gets closer to
the 11,000 points limit and thus approaches better what the user
wanted within the limits of Prometheus.
Note that in practice, the 11,000 points limit should never be of
relevance. (Even a 4k screen doesn't have 11k points on the x axis.)

* Prometheus: Display HELP and TYPE of metrics if available
- Prometheus recently added a metadata API around HELP and TYPE of
metrics
- request metadata when datasource instance is created
- use metadata to show help and type in typeahead suggestions and in
metrics selector as tooltip
* Fix types
* 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
