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.
