Cleanup virnetdevbandwidthtest and introduce new test cases.
However, Martin suggested (after glancing over the last patch) that
arguments could be stored in a file (just like qemuxml2argvtest does).
I'm not against that, but QEMU cmd line args change more often than
those of tc/ovs-vsctl. But if desired I can do the change (either as a
follow up or in v2).

New subject: [PATCH 1/4] virnetdevbandwidthtest: Drop unnecessary brackets
Some cases that call DO_TEST_SET() macro wrap each argument in
curved brackets. This is unnecessary, drop the brackets.

The last usage of the testMinimalStruct struct was removed in
v1.2.2-rc1~206 which forgot to remove the struct as well. Remove
it now.

New subject: [PATCH 3/4] virnetdevbandwidthtest: Reformat TC cmd line
Our coding style expects a long line to be broken into shorter
lines which are then aligned on the first character, for
instance:
"some string that's broken "
"into multiple lines"
However, one can argue that there are few cases where shifting
the alignment makes the code more readable. And this is the case
of expected cmd line for DO_TEST_SET() where a long cmd line can
be aligned on the arguments rather than the binary:
TC " filter ..."
" police ..."

New subject: [PATCH 4/4] virnetdevbandwidthtest: Test QoS for OVS
Ever since v7.6.0-rc1~235 we can use ovs-vsctl to set QoS instead
of tc. However, we don't have a test that's verifying generated
cmd line for ovs-vsctl.

I'm not against that, but QEMU cmd line args change more often than

I, personally, do not need that, I just figured it could be nicer for
someone.
Anyway, good that you added the tests, I remember the units were not fun
to figure out with the inconsistencies wrt tc, so it's good we have it
in the tests too now.
