增加trace和watch的复合参数 about arthas

[ralf0131]

What kind of input and output do you expect to have? Could you give an example?

[Hearen]

目前trace可以看到耗时，watch能看到入参和出参，希望有个命令即能够看到入参出参，同时能看到耗时？这样可以更方便的定位到底是因为什么参数导致比较慢？

Do you mean something like this:

$ watch -n 3 *Demo addTwoLists "params" -b
Press Ctrl+C to abort.
Affect(class-cnt:1 , method-cnt:1) cost in 216 ms.
ts=2018-10-13 11:08:04; [cost=0.659591ms] result=@Object[][
    @ArrayList[isEmpty=false;size=2],
    @ArrayList[isEmpty=false;size=2],
]
ts=2018-10-13 11:08:04; [cost=0.008653ms] result=@Object[][
    @ArrayList[isEmpty=false;size=2],
    @ArrayList[isEmpty=false;size=2],
]
ts=2018-10-13 11:08:04; [cost=0.010443ms] result=@Object[][
    @ArrayList[isEmpty=false;size=2],
    @ArrayList[isEmpty=false;size=2],
]
