Distribute through maven central and change groupId and base package

Current groupId of bucket4j is com.github, but Maven Central requires that groupId of artefact should be a controlled(by author) domain, so groupId should be changed, else it is not possible to publish artefacts to Maven Central:

• Change groupId from com.github to com.github.vladimir-bukhtoyarov
• Rename java package from com.github.bucket4j to io.github.bucket4j, domain for this package already reserved.
• Contact to Bintray support as mentioned in this topic in stackoverflow How to change groupid if project is already uploaded to bintray
• Integrate Bucket4j Bintray repo with Maven Central.

This issue originally raised in jhipster#5388

Proposed to release 2.0

Sorry, I didn’t realize your package name was different from your groupId, and in fact it should be, otherwise that’s quite confusing. What you could do, is what we did for for the JHipster library:

• The package name is “io.github.jhipster”, as we have the domain name “https://jhipster.github.io/” for free from GitHub -> you also have “io.github.bucket4j” for free.
• And to be consistent, our groupId is also “io.github.jhipster”, you can check the lib at http://search.maven.org/#artifactdetails|io.github.jhipster|jhipster|1.1.1|jar
