Function list API return more message

**Is your feature request related to a problem? Please describe.**

Now. function list API just return functions name and it's greate if return more message:

- Running [true/false]
- workerId ""
- Restarts (from status.numRestarts)

like this,

| NAME | RUNNING | RESTARTS | WORKERID |
| ---- | ---- | ---- | ---- |
| first | true | 0 | c-standalone-fw-localhost-8080 |
| second | false | 10 | c-standalone-fw-localhost-8080 |

**Describe the solution you'd like**

**Describe alternatives you've considered**

**Additional context**

I am not familiar with function code, but if want implement this function quickly and easily, Can process the code.

Request status API for every function name. I am not sure about that Quality and performance.

Componentlmpl#listFunctions

```
for (FunctionMetaData functionMetaData : functionStateList) {
if (InstanceUtils.calculateSubjectType(functionMetaData.getFunctionDetails()).equals(componentType)) {
*** get status ***
retVals.add(functionMetaData.getFunctionDetails().getName());
}
}
```

Start at ComponentImpl#listFunctions and trace how each function name is currently collected. Review the available status API and determine how running state, workerId, and status.numRestarts can be returned without an unacceptable per-function request cost. Done means the function list response includes the requested status fields and the relevant behavior is covered by the project's tests.
