SCB-915:saga alpha event scanner optimization

[oliugian]

omega do not send every try event to alpha.omega do it's try logic by itself.

@oliugian Did you run the accept test?
I'm not sure why did you delete the forward recovery test code?
BTW, I think we need to avoid the infinite loop of retry (-1) by default.

[oliugian]

All tests have been successful
The functionality of ForwardRecovery has been incorporated into defaultRecovery, so delete it and its test code. There is a test code equivalent to ForwardRecover in TransactionAspectTest.
(-1) means infinite retry, but it can also be interrupted, throwing an InterruptedException, which is consistent with the logic in the previous ForwardRecovery

[oliugian]

ignore it
