[MGPG-146] Flip bestPractice default value to TRUE

**[Tamas Cservenak](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=cstamas)** opened **[MGPG-146](https://issues.apache.org/jira/browse/MGPG-146?redirect=false)** and commented

The default value for `bestPractice` is currently `false` but user can flip it to `true` using plugin configuration.
Starting in 3.3.0 release, the default value of it will be flipped to `true`, leaving option for users to flip it to `false` via configuration.

Last, probably in 3.4.0 the complete set of related parameters (bestPractice and related deprecated ones) are going to be removed.

Locate the plugin configuration and the current default for `bestPractice`; no file or test is named in the issue. Change the default to true while preserving the option to configure it as false, then verify both default and explicit configuration behavior.
