MySQL integration test and fixed security risks

Summary

In this release we introduced the security risks check with ossindex-maven-plugin. We removed the reported security risks by updating or excluding third-party transient test dependencies. Those were used in the integration tests of the Virtual Schema for Hive.

We also adjusted the naming for the attached JAR file:

Old naming pattern: virtualschema-jdbc-adapter-dist-<dialects version>.jar

New naming pattern: virtual-schema-dist-<virtual schema common jdbc version>-bundle-<dialects version>.jar

The new naming pattern helps users to distinguish minor dialect changes from major adapter changes affecting all dialects.

Bug Fixes

• #336: Fixed broken links in the documentation.
• #343: Added ossindex-maven-plugin plugin and removed found security risks in transient dependencies.

Features / Enhancements

• #340: Added MySQL dialect integration test.
• #346: Added changelog.md file to the documentation for keeping tracking of changes outside of the github.
• #348: Added Version Maven Plugin for tracking new available versions of dependencies and plugins, updated dependencies
