Before it used to output the violations all one one line. Now it looks
like:
```
MozillaStrictModeSuppression:
'import mozilla.components.support.ktx.android.os.resetAfter' at
(17,1) in /StrictModeManager.kt
Please use `components.strictMode.resetAfter` instead because it has
performance improvements and additional code to monitor for performance
regressions.
MozillaStrictModeSuppression:
'setThreadPolicy(threadPolicy.build())' at (56,24) in
/StrictModeManager.kt
Please use `components.strictMode.resetAfter` instead because it has
performance improvements and additional code to monitor for performance
regressions.
MozillaStrictModeSuppression:
'setVmPolicy(builder.build())' at (71,24) in /StrictModeManager.kt
NOT YET IMPLEMENTED: please consult the perf team about
implementing`StrictModeManager.resetAfter`: we want to understand the
performance implications of suppressing setVmPolicy before allowing it.
```
Add a custom detekt rule to blacklist certain properties. This is
immediately useful for making sure that developers do not configure
runtime behavior using the `BuildConfig.DEBUG` property but it is
useful in a wider context.
