Set command does not validate given value

[arina-ielchiieva]

Set command allows to set non integer value for ALL properties that require numeric values, after that queries fail to execute:

0: jdbc:drill:zk=local> !set headerInterval xxx
0: jdbc:drill:zk=local> !set headerinterval 
headerinterval      xxx
0: jdbc:drill:zk=local> select * from sys.version;
java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Integer

set isolation command does not check if value is valid.
The same is for timestampFormat, dateFormat and timeFormat.

0: jdbc:drill:zk=local> !set isolation xxx
0: jdbc:drill:zk=local> !set isolation 
isolation           xxx

set outputFormat does not validate given value and then outputs warning during query execution:

0: jdbc:drill:zk=local> !set outputformat xxx
0: jdbc:drill:zk=local> select * from sys.version;
Unknown output format "xxx". Possible values: [xmlattr, tsv, xmlattrs, xmlelements, csv, json, vertical, table]

Better to output usage warning like for reset command:

0: jdbc:drill:zk=local> !reset
Usage: reset (all | <property name>)
