Explore: Metrics chooser for prometheus

- 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
