Gradle (#233)

* Build BDK using Gradle Use Gradle instead of Maven for faster builds thanks to incremental support! Most of the configuration is at the root level and applied to all subprojects. Sub projects mostly define their dependencies. Use the Java platform support to implement Maven BOM and align dependencies. Gradle wrapper can be used to build. Circle CI configuration has been updated. Jenkins configuration for release is not yet migrated. Code coverage configuration for legacy BDK felt off, we need to review it together. * Code coverage configuration for legacy Put back BUNDLE coverage and use the current value for coverage check * Remove unused method * Put back Maven wrapper for now * Support Snyk scan Repositories were not defined for BOM
