Bug 1239037

Description of problem:
Wrong Values for "cluster.heal-timeout" option could be set.
gluster v set cluster.heal-timeout <value> is taking any value. Very large number, 0 or even negative.
Don't see any wrong behavior for volume but gluster v info shows wrong values are set for this option.

How reproducible:
100%

Steps to Reproduce:
1. Create disperse volume.
2. set cluster.heal-timeout for any unexpected value (large, 0 or negative number)
[root@rhs3 ~]# gluster v start test
volume start: test: success
[root@rhs3 ~]# gluster volume set test cluster.heal-timeout -1222666666666666666666
volume set: success

3. run gluster v info test. It displayes wrong values given on cli

Actual results:
CLI is accepting and setting wrong values for cluster.heal-timeout

Expected results:

There should be a check on the given values. A proper message should be displayed for wrong values provided.
