backoff under retryStrategy does not work as expected for version 3.3.8

[Ali-RT]

The backoff feature for retryStrategy does not behave as expected under version 3.3.8.

      retryStrategy:
        limit: "10"
        backoff:
          duration: "30m"   

The workflow was retried 10 times, but the wait time between each retry call was about 21 seconds.

Tested under version 3.2.4, and it worked as expected.

@dpadhiar Can you try to reproduce this issue?

[dpadhiar]

@sarabala1979 Yes.

@sarabala1979 Confirmed backoff duration isn't working on 3.3.8.

Hi @sarabala1979 @dpadhiar ! Do you think this can be fixed in a new release soon? It's the only thing preventing us from deploying to production so far.

[dpadhiar]

@raafatseif Yes, we will look into getting this fixed before 3.3.9/3.4 is released.

To add to this, I've tested against v3.3.7 where the Backoff duration is working. This issue must have been introduced between v3.3.7 and v3.3.8.

Could we also add a required unit test for this to prevent regression in the future?

@HRusby I was able to reproduce the issue in v3.3.7
