Elytron integration with Batch / JBeret

A new {{security-domain}} attribute was added to the {{batch-jberet}} subsystem to allow batch jobs to be executed under that security domain. Jobs that are stopped as part of a {{suspend}} operation will be restarted on execution of a {{resume}} with the original user that started job. There was a {{org.wildfly.extension.batch.jberet.deployment.BatchPermission}} added to allow a security restraint to various batch functions. The following functions can be controlled with this permission. * start * stop * restart * abandon * read The read function allows users to use the getter methods from the {{javax.batch.operations.JobOperator}} or read the {{batch-jberet}} deployment resource, for example {{/deployment=my.war/subsystem=batch-jberet:read-resource}}.
