Split JDBC Driver into it's own repository

[acarbonetto]

Is your feature request related to a problem? Please describe

As mentioned under #2692, the JDBC Driver is deployed alongside the SQL plugin in the SQL plugin repo. However, the JDBC driver should follow its own CI/CD process and release versioning instead of depending on the SQL plugin. These are separate release artefacts and they should have their own separate repository project.

Describe the solution you'd like

Move SQL-JDBC folder into it's own project repository under the OpenSearch project.

Describe alternatives you've considered

Alternatives (such as the status quo) means that repositories will be responsible for multiple release artefacts, which is less ideal.
