Feature monitoring for scalar features.

SQL schema:
For numeric features

feature_name | feature_type | mean | median | max | min | coverage |

For string/boolean features:

feature_name | feature_type | cardinality | coverage

coverage = (total_count - missing_count) / total_count
cardinality = count of different items. For example, ["apple", "apple", "orage" ] => cardinatily is 2(apple and orange)

For example:
input feature table:

+----+------+--------+-----+--------------------+---------+
|key0|f_null|f_string|f_int|            f_double|f_boolean|
+----+------+--------+-----+--------------------+---------+
