Review Comment:
> initialization lazy
Here we have some more consideration:
During planned and optimized **metaclient** or **fileindex** might be used
by different rules' **hoodie source** copy instances for multi times.
For example, actually **fileindex** is used in
**PushPartitionIntoTableSourceScanRule** and
**PushFilterIntoSourceScanRuleBase**
So it seems that initialization lazy will also cause the multi construction ?
