BUG#48048: Deprecated constructs need removal in Betony

Post-push fix: Removed MTRv1 arguments according to the
original patch. Although there is a version check, the patch
was pushed to a 5.1 GA staging tree, while the version check 
considers version 5.2. This makes the deprecated parameters 
to be used, despite the fact that they are not valid anymore.

Part of MTRv1 is currently used in RQG semisync test, and this
was causing the test to fail on slave startup.

It should be safe to uncomment when merging up to celosia.
