The current table transform renders only the first query.
This PR adds a new transform to render all query results in a JOIN-ish
semantic.
* new table transform: Multi-Query table
* columns is the union of all non-value fields
* one value column per query is added
* rows that share all the same label values are merged into one

Avg column was being added at every rendering, if the table was empty.
Now the column will be added once as an initialization when selecting a
'timeseries_aggregations' transform.
