Add a local clone of javaFormatter plugin. The upstream is not maintained anymore. And we need to update it to use the newest Google java formatter because the old one, that we use, cannot format sources with Java 8+ syntax. # Important Notes Update to Google java formatter 1.18.1 - https://github.com/google/google-java-format/releases/tag/v1.18.1

/** A local fork of https://github.com/sbt/sbt-java-formatter. The original plugin uses a very outdated version
|
|
* of `google-java-format` dependency which does not support syntax > JDK8. It's unlikely we will see the
|
|
* dependency upgraded any time soon, if ever, hence the almost one-to-one copy of the plugin.
