GH-3733 Configure TxManager for DefLockRepository (#3782)

Browse Source 
* GH-3733 Configure TxManager for DefLockRepository

Fixes https://github.com/spring-projects/spring-integration/issues/3733

The `@Transactional` resolves a primary `TransactionManager` bean
from the application context which might not be sufficient for all
the use-case.

To make it work with the custom (or specific) `TransactionManager`
we have to extend a `DefaultLockRepository` and override all those
`@Transactional` method

* Change the logic of the `DefaultLockRepository` from `@Transactional`
to the `TransactionTemplate` and use provided `TransactionManager`
or resolve one from the application context
* Adjust tests to use explicit `TransactionManager` and call
`afterSingletonsInstantiated()` to initialize a default `TransactionTemplate`
* Mention the change in the docs

* * Extracted all the `TransactionTemplate`s to the properties for caching
* Add `BeanInitializationException` for no-unique `PlatformTransactionManager`
bean in the `afterSingletonsInstantiated()`

* Fix language in the exception message
