A handful of things that will make iteration a bit easier. This is all really hard to do in separate tickets or in a staged way. Smaller PRs first wherever possible, but minimize times we backport. Best to just rip off the bandaid.

Changes to sys-perf yamls (master and 4.4):

1. Single f_run_dsi_workload Evergreen function
   1. Mostly the same logic that's currently in the handful of existing functions, but in a single function.
   2. Update the param names to match the files e.g. cluster to infrastructure_provisioning
   3. Use conventional module locations where possible
   4. Use conventional report output locations where possible
   5. Remove cruft like dsienv.sh; run-dsi invocations are single-line scripts
2. Change the order of tasks/functions to keep compile and dsi stuff more separated.
3. Add a genny task that is not a generated task.

Changes to microbenchmarks yamls (master and 4.4):

1. Single f_run_microbenchmarks_workload evergreen function for non-genny workloads
2. Single f_run_genny_workload evergreen function for genny workloads
3. Both functions to use conventional module locations where possible
4. Remove extraneous genny invocation--I think just need the call to lamp without venv nonsense
5. Tidy the weird pkill logic
6. Conventional locations for genny, DSI, and signal-processing modules
7. Change the order of tasks/functions to keep compile, dsi, and non-dsi-based-workloads more separated.

Changes to DSI:

1. Update for conventional paths above
2. Make evergreen-dsitest.yml a representative snapshot of what's in system_perf.yml and, if possible, something similar for perf.yml
3. Change documentation for how to patch-build without compile

Changes to Genny:

1. Kill "legacy" task-gen logic
