vmselect: fix label_replace when mismatch ( #579 )
...
As per documentation on `label_replace` function: "If the regular
expression doesn't match then the timeseries is returned unchanged".
Currently this behavior is not enforced, if a regexp on an existing
tag doesn't match then the tag value is copied as-is in the destination
tag. This fix first checks that the regular expression matches the
source tag before applying anything.
Given the current implementation, this fix also changes the behavior
of the **MetricsQL** `label_transform` function which does not
document this behavior at the moment.

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.
