This is the first step moving towards Explore supporting logs for
more datasources than Loki. In the first step we move all the log
processing from Loki into Explore.
- Make explore convert logs result returned from datasources to SeriesData,
if needed, and for now convert SeriesData to LogsModel.
- Loki datasource query now returns SeriesData and all
processing have been moved into explore instead.
- Removed key from LogRowModel and use log row indexes as
the unique key instead.
- Removed id from LogsModel since it looks like it's not in use.
- Introduced a new class FieldCache which is convenient to use when
looking up multiple fields and/or field types and series values.
Closes#16287
Fixes#15635
Importing ansicolor from node_modules or vendored as is failed because
there is no ES5 transpiler configured for ES6 libs.
- remove ansicolor from package.json
- add ansicolor to public/vendor/ansicolor and port to typescript
- adapt all ansicolor imports
- add `public/vendor` as a path to be considered by ts compiler
