Before this commit, EnableBatchProcessing was tied to a JDBC
infrastructure. Therefore, it was impossible to use a non-JDBC
job repository with that annotation.
This commit removes the dependency to a JDBC infrastructure from
EnableBatchProcessing and introduces new annotations to configure
specific job repository implementations. It also updates the
programmatic way of configuring infrastructure beans with a base
configuration class for each supported job repository implementation.
NB: The XML namespace was not changed accordingly as the XSD will not
be updated starting from v6.
