DART Reduction unreliable with file imported data

[ghost]

When importing data into DART from files instead of streaming, decommutation can become many minutes out of order when spread across processes. This isn't inherently wrong, but can cause reduction to think that data is ready to be reduced when it is not all available yet. This change will modify:

1. Make reduction have a 2 minute holdoff to ensure all data is available
2. Change decom to a work queue design to ensure that packets do not get multiple minutes out of processing order
3. Improve decommutation speed using transactions
4. Don't try to switch to bad configs multiple times

@aaronatball I believe this fixes your reduction issues

Awesome, I will check this out the next time I'm doing DART stuff!
