58cb7fc476 app/vmselect: adjust label_map() handling for corner cases 
The following corner cases now supported:
* label_map(q, "label", "", "foo") - adds `label="foo"` to series with missing `label`
* label_map(q, "label", "foo", "") - removes `label="foo"` from series

All the unmatched labels are kept unchanged.

This flag can be used for removing gaps on graphs if the difference between the current time
