* Performance: Standardize lodash imports to use destructured members
Changes lodash imports of the form `import x from 'lodash/x'` to
`import { x } from 'lodash'` to reduce bundle size.
* Remove unnecessary _ import from Graph component
* Enforce lodash import style
* Fix remaining lodash imports
* Chore: removed regex from LokiQuery
* Chore: removes parseQuery from Loki datasource
* Chore: removes regex param from format query in lokiStreamsToDataframes in Loki result transformer
* Chore: updates formatQuery and removes parseQuery from Loki query utils
* Chore: removes highlighter test with unsupported syntax from Loki query utils
* (feat/explore): Support for new LogQL filtering syntax
Loki is adding syntax to support chained filtering.
This PR adapts Grafana to support this.
- Send only `query` parameter in loki request
- Automatically wrap search text in simple syntax, e.g., `{} foo` is
sent as `{} |~ "foo"`.
* Adapted to regexp parameter staying on in Loki
* Dont wrap single regexp in new filter syntax
* Fix datasource test
* Fallback regexp parameter for legacy queries
* Fix search highlighting
* Make highlighting work for filter chains
* Fix datasource test
- add second query field to logging datasource query component
- second field manages search term, first field manages stream selectors
- improved logging cheat sheet to get started
