DRILL-6248: Added limit push down support for system tables
1. PojoRecordReader started returning data in batches instead of returing
all in one batch. Default batch size is 4000.
2. SystemTableScan supports limit push down while extrating data in record
reader based on given max records to read.
3. Profiles and profiles_json tables apply limit push down while extracting
data from store accessing profiles by range.
Details in [DRILL-6248](https://issues.apache.org/jira/browse/DRILL-6248).
