Mechanism for isSameRM override for unwrapped resources

Some connection pool implementations (DBCP for example) do not have a mechanism for wrapping XAResources so that we can control or override the behaviour of the resource. For example the implementation of isSameRM is know to be a problem with some drivers.

To overcome this limitation we would like to have a config property containing a list of XAResource types for which we should override the isSameRM call forcing it to return true. This is a workaround only and the longer term plan is ensure that the connection pool from which resources are taken has a mechanism for overriding it (as for example IronJacamar did but Agroal doesn't).
