Add support to validate job repository configuration

[fmbenhassine]

As of v5.2, it is assumed that the job repository is correctly configured and there is no pre-validation that everything is setup correctly before running a job. Therefore, any mis-configuration of the job repository results in SQL exceptions or NPE like this or #4811 .

The goal of this issue to explore the best way/place to check the configuration of the chosen job repository upfront and fail fast with an informative BatchConfigurationException rather than an SQL exception or a NPE.
