Prior to this commit, if an application had multiple PlatformTransactionManager beans it would fail to start even when configuring a proper TransactionOperations qualified bean.
This commit introduces the @SpringSessionTransactionManager bean qualifier to specify which bean should be injected into Spring Session JDBC configuration, if no bean specified, it tries to resolve a unique PlatformTransactionManager bean from the application context to maintain backward compatibility.
Closes gh-2801
