### What problem does this PR solve?
Issue Number: close #xxx
Related PR: #xxx
Problem Summary:
expression add min max scope for slot reference, so that olap scan can
reduce field's searching scope.
detail: in simplify range rule, record min and max range of the slot
reference, then add 'e > min and e < max' to the expression.
example:
```
TA >= 10 and TA <= 20 or TA >= 50 and TA <= 60 or TA >= 100 and TA <= 120
=> (TA <= 20 or TA >= 50 and TA <= 60 or TA >= 100) AND TA >= 10 and TA <= 120
TA in (10, 50, 100) or TA >= 70 and TA <= 90 => (TA in (10, 50, 100) or TA
>= 70 AND TA <= 90) AND TA >= 10 AND TA <= 100
TA between 10 and 20 and TB between 10 and 20 or TA between 100 and 120 and
TB between 100 and 120 => (TA <= 20 and TB <= 20 or TA >= 100 and TB >= 100)
AND TA >= 10 AND TA <= 120 AND TB >= 10 AND TB <= 120
ISNULL (TA > 10) and TA > 10 and TA < 20 or TA > 50 and TA < 60 or TA > 100
and TA < 120 => (ISNULL(TA > 10) and TA < 20 or TA > 50 and TA < 60 or TA >
100) AND TA > 10 and TA < 120
```
