Disable schema validation when testing against Hazelcast 3

We have hazelcast configuration files that are used with multiple
versions of Hazelcast. Version 3's scheme doesn't allow us to set
<auto-detection enabled="false" />. To work around this, we
configure a system property that causes Hazelcast to disable schema
validation.

See gh-38163
