Support array result include sequence action

[ningyougang]

Depend on below prs:

• Support array result for common action and sequence action openwhisk#5290

• Support array result include sequence action openwhisk-runtime-go#170

• Support array result

  • make swift runtime to support array result for common action
  • make swift runtime to support array result for sequence action (support array as input param)

The steps of test support array result for sequence action in swift(4.2, 5.1, 5.3)

• Write actions

[root@nccddev130026 ~]# cat ~/split.swift 
func main(args: Any) -> Any {
    // don't do real split operation, just return array for next action's input param
    return ["e1", "e2"]
}

[root@nccddev130026 ~]# cat ~/sort.swift 
func main(args: Any) -> Any {
    // don't do real sort operation, just return the array direclty
    return args
}

• Create actions and invoke it

wsk -i action create /whisk.system/utils/split-swift --kind swift:5.3 ~/split.swift
wsk -i action create /whisk.system/utils/sort-swift --kind swift:5.3 ~/sort.swift
wsk -i action create mySequence-swift --sequence /whisk.system/utils/split-swift,/whisk.system/utils/sort-swift
wsk -i action invoke --result mySequence-swift -r -v

In order to support array result, from the new main signature. we can see, the the input param and outout param should be changed to Any both.

Need to change it to release due to apache/openwhisk-runtime-java#140 (comment)

[ningyougang]

Already changed to release
