[Why] With template compare mode, it's useless return an empty changes for a metric like: { ... "tables": { "vmstat.system.cs": { ... "change": { "dimensions": [ "compare_dimension" ], "source": [ [ "8G", "16G" ] ] } } }

[How] Skip assign metric change value, if the metric only have one dimension, the empty change will disappear automatically
