Refactors some of the code in VXNetworkInterface to handle MTUs in a
more streamlined fashion. Also fixes a bug whereby bridge client
networks were being explicitly given the cluster dev MTU which might not
be correct. Now adds support for this option explicitly in the configs,
and defaults to 1500 for safety (the standard Ethernet MTU).
Addresses #144
When using the "state", "node", or "tag" arguments to a VM list, add
support for a "negate" flag to look for all VMs *not in* the state,
node, or tag state.
1. Remove ramp_time as this was giving very strange results.
2. Up the runtime to 75 seconds to compensate.
3. Print the fio command to the console to validate.
1. Runs `fio` with the `--format=json` option and removes all terse
format parsing from the results.
2. Adds a 15-second ramp time to minimize wonky ramp-up results.
3. Sets group_reporting, which isn't necessary with only a single job,
but is here for consistency.
Allows choosing different list and info functions based on the benchmark
version found. Currently only implements "legacy" version 0 with more to
be added.
Adds a test_format database column and a value in the API return for the
test format version, starting at 0 for the existing format as of 0.9.37.

1. Move to a time-based (60s) benchmark to avoid these taking an absurd
amount of time to show the same information.
2. Eliminate the 256k random benchmarks, since they don't really add
anything.
3. Add in a 4k single-queue benchmark as this might provide valuable
insight into latency.
4. Adjust the output to reflect the above changes.
While this does change the benchmarking, this should not invalidate any
existing benchmarks since most of the test suit is unchanged (especially
the most important 4M sequential and 4K random tests). It simply removes
an unused entry and adds a more helpful one. The time-based change
should not significantly affect the results either, just reduces the
total runtime for long-tests and increase the runtime for quick tests to
provide a better picture.
Ensure that all keepalive timeouts are set (prevent the queue.get()
actions from blocking forever) and set the thread timeouts to line up as
well. Everything here is thus limited to keepalive_interval seconds
(default 5s) to keep it uniform.
Remove two superfluous synchronization steps which are not needed here,
since the exclusive lock handles that situation anyways.
Still does not fix the weird flush->unflush lock timeout bug, but is
better worked-around now due to the cancelling of the other wait freeing
this up and continuing.
