Support array result include sequence action

[ningyougang]

Depend on below prs:

• Support array result for common action and sequence action openwhisk#5290 (have merged)

• Support array result include sequence action openwhisk-runtime-go#170 (have merged)

• Support array result

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

sequence action also supports by default(includes 2.5 and 2.6), test steps as below

• Write split.rb and sort.rb

[root@nccddev130026 ~]# cat split.rb 
def main(args)
  payload = args["payload"] || "aaa\nbbb\ncccc"
  separator = args["separator"] || "\n"
  result=payload.split(separator)
  puts result
  result
end

[root@nccddev130026 ~]# cat sort.rb 
def main(args)
  newResult = args.reverse
  puts newResult
  newResult
end

• Create sequence action and invoke it (I tested ruby:2.5/2.6, worked well both)

wsk -i action create /whisk.system/utils/split-ruby --kind ruby:2.5 ~/split.rb
wsk -i action create /whisk.system/utils/sort-ruby --kind ruby:2.5 ~/sort.rb
wsk -i action create mySequence-ruby --sequence /whisk.system/utils/split-ruby,/whisk.system/utils/sort-ruby
wsk -i action invoke --result mySequence-ruby --param payload "dddd\nbbbb\ncccc\nfffffff\nggggggggg" -r -v
