Since every mocked clock time step also waits for 1ms to give other
goroutines a chance to run, it took too much wallclock time to mock-sleep
for 47 seconds with 100ms increments.
Stepping the mocked clock with 1s increments makes the test 10x faster.
Some parts of Flamenco had a Command consist of "name + settings", and
other parts used "type + parameters" (with the same semantics). This is
now unified to "name + parameters".
