Add TransactionTemplate auto-configuration
Provide a TransactionTemplate if one PlatformTransactionManager is present. Relocated the jta support as a nested package of the new transaction package that hosts the transaction template auto-configuration. To avoid package tangles, links between auto-configurations have been reversed. Closes gh-2464 Closes gh-2809pull/2770/merge
