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

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

[ningyougang]

Supports sequence action for dockerskeleton:support, the test steps as below

• Write codes

[root@nccddev130026 ~]# cat exec 
#!/bin/bash
echo '["a", "b"]
[root@nccddev130026 ~]# zip -r splitAction.zip exec

[root@nccddev130026 ~]# cat exec 
#!/usr/bin/env bash

arr=$1

echo $arr
[root@nccddev130026 ~]# zip -r sortAction.zip exec

• Create action and invoke action

wsk -i action create /whisk.system/utils/split-docker splitAction.zip --docker reg.navercorp.com/lambda/dockerskeleton:support-array-result
wsk -i action create /whisk.system/utils/sort-docker  sortAction.zip --docker reg.navercorp.com/lambda/dockerskeleton:support-array-result
wsk -i action create mySequence-docker --sequence /whisk.system/utils/split-docker,/whisk.system/utils/sort-docker
wsk -i action invoke mySequence-docker -r -v
