Moved bullets to the separate features

This feature (as I see, feel free to add comments)

provide a cli (Linux binary) with incorporated drivers which can migrate all the supported databases

Note for me: revive old -standalone module, without maven-antrun-plugin, use spring-boot-plugin for both creating image and native binary, the plugin should be mature enough.
Use Github's artifact storage to store both binary and jar
