Get the stability test ready

[macxu]

we have an example at:

"lepv/app/tests/profilers/cpu/GetProcLoadavg/stabilityTests.py"

the idea is to ensure that:

1. a profiler method can talk to a live LEPD server ( say, rmlink.cn ), and get the response.
2. the profiler can parse the response, organize it in a structured way.
3. the structure confirm to our expected way, to be specific:

• ensure expected properties are in place.
• ensure some properties are of the expected type ( int, float, percent, enum etc ).
• ensure we can get the expected result 50 times in a row without any error. ( this is vital )
• log the elapsed time for each call, making sure it is reasonable.
