GitLab could already be used as an authentication backend by properly
configuring `auth.generic_oauth`, but then there was no way to authorize
users based on their GitLab group membership.
This commit adds a `auth.gitlab` backend, similar to `auth.github`, with
an `allowed_groups` option that can be set to a list of groups whose
members should be allowed access to Grafana.
* Explore: Query hints for prometheus
- time series are analyzed on response
- hints are shown per query
- some hints have fixes
- fix rendered as link after hint
- click on fix executes the fix action
* Added tests for determineQueryHints()
* Fix index for rate hints in explore
- load all histogrammable metrics on start, based on `{le!=''}` series
query
- select dropdown shows all those metrics as well as histograms in a
special group
- select a metric will write fill the metric in the query box
- if a histogram is chosen, it will write a complete
`histogram_quantile` query
- added new dependency: rc-cascader
- Clear All button to clear all queries and results
- moved result viewer buttons below query rows to make it more clear
that they govern result options
* Add click on explore table cell to add filter to query
- move query state from query row to explore container to be able to set
modified queries
- added TS interface for columns in table model
- plumbing from table cell click to datasource
- add modifyQuery to prometheus datasource
- implement addFilter as addLabelToQuery with tests
* Review feedback
- using airbnb style for Cell declaration
- fixed addLabelToQuery for complex label values
* Refactor Explore query field
- extract typeahead field that only contains logic for the typeahead
mechanics
- renamed QueryField to PromQueryField, a wrapper around TypeaheadField
that deals with Prometheus-specific concepts
- PromQueryField creates a promql typeahead by providing the handlers
for producing suggestions, and for applying suggestions
- The `refresher` promise is needed to trigger a render once an async
action in the wrapper returns.
This is prep work for a composable query field to be used by Explore, as
well as editors in datasource plugins.
* Added typeahead handling tests
- extracted context-to-suggestion logic to make it testable
- kept DOM-dependent parts in main onTypeahead funtion
* simplified error handling in explore query field
* Refactor query suggestions
- use monaco's suggestion types (roughly), see
https://github.com/Microsoft/monaco-editor/blob/f6fb545/monaco.d.ts#L4208
- suggest functions and metrics in empty field (ctrl+space)
- copy and expand prometheus function docs from prometheus datasource
(will be migrated back to the datasource in the future)
* Added prop and state types, removed unused cwrp
* Split up suggestion processing for code readability
- new builtin datasource plugin "Logging" (likely going to be renamed)
- plugin implements no panel ctrls yet, only ships datasource
- new models for logging data as first class citizen (aside from table
and time_series model)
- Logs as new view for Explore
- JSON view for development
Testable only against existing logish deployment.
Then test with queries like `{job="..."} regexp`.
Adds a datasource selector to the Explore UI. Only datasource plugins
that have `explore: true` in their `plugin.json` can be selected.
- adds datasource selector (based on react-select) to explore UI
- adds getExploreSources to datasource service
- new `explore` flag in datasource plugins model
- Prometheus plugin enabled explore
* Rewriting team pages in react
