Change subject: [metrics] Add a metric to count merged entities when merge
metrics

[metrics] Add a metric to count merged entities when merge metrics
When metric entities merged to a new entity, we don't know how many
entities it merged from.
This patch add a new metric 'merged_<entity>_entities_count' to entity
and set value to 1, then the new merged entity will have the same
metric with value merged.
We can use this information to check whether a table is balanced or
not by thirdparty monitor system efficiently. Though we can use CLI
tool like 'kudu cluster rebalance' to check per-table balance status
of a cluster, but we have to fetch balance info table by table (by add
--tables=xx flag), and also we have to "run command" in thirdparty
monitor system and this tool seems not fast enough because it will
call functions like RetrieveAllTablets.
