This change allows reads of our native users and roles when the template version has not been updated to match the current version. This is useful for rolling upgrades where the nodes are also being actively queried and/or indexed into. Without this, we can wreak havoc on a cluster by causing exceptions during replication, which leads to shard failures. On nodes that match the version defined in the template, write operations are allowed since we know that we are backwards compatible in terms of format but we may have added new fields and shouldn't index them until the mappings and template have been updated. As part of this, the rolling upgrade tests from core were used as the basis for a very basic set of tests for doing a rolling upgrade with x-pack.
