Improve the behavior when metric queries change
When the metric queries change, all the configured metrics are 'not found', so it requires re-mapping the query to each trace.
Rather than saving the explicit name, maybe we should save the reference and index? For example A.value|time|index
Original Issue Report:
This issue concerns X, Y, and Z names but for brevity I'll just mention X.
The runtime error "Unable to find X:" is thrown when an "ALIAS BY" pattern is specified in an InfluxDB query for the X (first) series. It looks like this is because in onDataReceived the name of the X data set is cached in this.panel.pconfig.mapping the first time a query runs. When the "ALIAS BY" query clause is changed and the query runs again the name of the X data settings doesn't get updated because this.panel.pconfig.mapping.X is already set.
I'm not sure what the name caching is for, but having the dmapping.x value always overwrite the mapping.x value seems to work without any obvious side effects.
