CC-19887: Getting rid of ojdbc8-production-19.7.0.0.pom

[ManasjyotiSharma]

CC-19887: Remove non-binary file (.pom file) from the lib folder of JDBC connector.

The dependency "ojdbc8-production" of type pom is a shorthand but it add itself as a dependency (i.e. the pom ojdbc8-production-19.7.0.0.pom itself is packaged). So instead of that shorthand; depending on the actual jar deps. See this for context.

Does this solution apply anywhere else?

@ManasjyotiSharma - should we scope to runtime explicitly ?
