Closes#4027Closes#3656
This commit removes the deprecated Map-based job repository
and job explorer implementations with their respective DAOs.
Using the `EnableBatchProcessing` annotation now requires a
datasource bean to be defined in the application context.
This will be reviewed as part of #3942.
This commit is a first pass that updates related tests to use
the JDBC-based job repository/explorer with an embedded database.
A second pass should be done to improve tests by caching/reusing
embedded databases if possible.
Issue #3836
Add EPUB output and make all four output formats have links to one another,
to enable discoverability and accessibility (for the folks who need a
particular format to help them read the document).
The sample that shows how to provide a custom transaction manager
via a BatchConfigurer has been updated to use the constructor
of `DefaultBatchConfigurer` that takes a DataSource.
