perf test: Add -w/--workload option
The -w/--workload option is to run a simple workload used by testing.
This adds a basic framework to run the workloads and 'noploop' workload
as an example.
$ perf test -w noploop
The noploop does a loop doing nothing (NOP) for a second by default.
It can have an optional argument to specify the time in seconds.
