Description

When existing sub-device, getLeafCount() may get wrong result.
For example:
We have 3 timeseries: root.a.b.c, root.a.b.c.d, root.a.b.c.d.e
The "leaf" count of root.a should be 3: c, d and e, which represents the number of timeseries.

Besides, the function name is also ambiguous, which should be modified to getMeasurementMNodeCount.
