-----------------------------------------

I'm cloning the JBEAP-17611 to track the {{:recover}} call as a WFLY feature request.

> Based on the operator work at https://github.com/wildfly/wildfly-operator it seems that the operations required by the admin to perform recovery are quite complex.
> It seems that the customer must to:
> 1. make sure that tx recovery listener is enabled in the tx subsystem
>   1.a read the correct port from the socket binding, don't forget to also read the portOffset and take it into account
> 2. connect to this tx-recovery-port opened by the server and send a SCAN command
> 3. read the Pod log with a regexp "ERROR.*Periodic Recovery"
>    3.a don't forget to timestamp the logs
> 4. read recursively all tx logs to check that there are no in-doubts tx
> Oh and if you want to configure the tx recovery process, please add the correct system properties om.arjuna.ats.arjuna.common.Recovery*
> This creates a lot of complexities for the customer (and the operator code) that should be encapsulated by the transactions subsystem.
> Tthe subsystem should provide a :recover management operation
> that deals with connecting with Narayana (no need to open a socket since Narayana is IN-VM) and perform the scan / logs checking / etc. and return the useful information to the user (the in-doubt TX)
> Likewise, any recovery configuration should be handled by the transactions and not through System properties.
