Title:

Add the high value workloads to the 4.4 branch

Description:

This ticket covers adding the high value workloads to the 4.4 branch. We'll need to check which are possible to run (e.g. the timeseries workloads wouldn't work on 4.4 since the feature was added in 5.0) and then add them.

Context:

For example, it looks like we are running ycsb_60GB, but not ycsb_60GB.long
