this is a fix-up PR that cleans up Explore Logging after the recent
restructuring.
- log results need to be merged since query transactions have been
introduced
- logging DS has its own language provider, query field, and start page
(some of them based on prometheus components)
- added loader animation to log viewer
- removed logging logic from prometheus components
* Add new build info metrics that contains more info
The goal was to add more information about Grafana. But rather than
just adding those to the current metrics I created a new metric
since its a common pattern in the prometheus community to expose that
info in a metric named `*_build_info`.
We keep the old metric to avoid introducing any breaking changes but
we should be able to remove it the next breaking change
- using grunt-newer to prefix precommit tasks
- only got it to work for tslint and tsc
Not applied to:
- sasslint does not take the file arguments in a way that grunt-newer
recognizes
- no-only-tests throws an error when used with `newer`, but it's
sub-second runtime
- when instantiating a datasource, the datasource service checks if the
plugin module exports Explore components, and if so, attaches them to
the datasource
- Explore component makes all major internal pluggable from a datasource
`exploreComponents` property
- Moved Prometheus query field to promehteus datasource and registered
it as an exported Explore component
- Added new Start page for Explore, also exported from the datasource
The grafana_stats.json used the following prometheus query: "increase(grafana_alerting_result_total[1m])" But a metric called "grafana_alerting_result_total" is currently not there anymore. So i changed the query to "increase(grafana_alerting_active_alerts[1m])" and updated the title as well (Before: "Grafana alert results", Now: "Grafana active alerts").
- added `node_modules` as new target
- dependency on `package.json` and `yarn.lock` allows for quick `make
node_modules` after a branch change, which noops when the deps have
not changed
- also added `clean` target
