DRILL-5838: Fix MaprDB filter pushdown for the case of nested field (reg.
of DRILL-4264)
Please see [DRILL-4264|https://issues.apache.org/jira/browse/DRILL-5838]
for the problem description.
`FieldPath.asPathString()` returns string in which field names may be
quoted if `FieldPath` instance was created from the string, in which these
fields were quoted. `SchemaPath.toExpr()` returns string were all field names
are quoted.
- Created new method in `SchemaPath` which quotes only field names which
contain dots.
- Fixed existing MaprDB unit tests to handle this case.
