Suggestions for improvement: Information on the variable and what can be set should be provided.

@Brandi - note that this for 3.2 docs onwards.
Hi Eric and Zhanqi, I opened PR#3723[1] to change the value from `true` to `1` in our OpenShift Container Platform 3.2 documentation. Please take a look. Do you think it is necessary to add the option of using either value in the other versions? If so I can add a note accordingly. Thanks! [1] https://github.com/openshift/openshift-docs/pull/3723
Verified this bug yes, this DROP_SYN_DURING_RESTART only can be accepted '1' in 3.2. for 3.3 or later, it will be accepted '1' and 'true'.
