title: Ask-cli lambda command uses wrong region setting
body: <p>I am trying to set up a workflow via the ask-cli for developing an Amazon skill with an Amazon lambda backend. I have created a skill and it works fine when using "ask api ..." commands, but when I use an "ask lambda ..." command, such as "ask lambda download -f MySkill", it uses the wrong region setting. I get the error:</p>
  
  <pre><code>ResourceNotFoundException: Function not found: arn:aws:lambda:us-east-1:123456789:function:MySkill
  </code></pre>
  
  <p>As you can see, it is looking for the lambda instance in us-east-1. But My lambda instance is in eu-west-1, as specified in my skill.json file below. This questions is pretty much a duplicate of <a href="https://forums.developer.amazon.com/questions/87922/ask-cli-does-not-use-region-setting-from-aws-confi.html" rel="nofollow noreferrer">https://forums.developer.amazon.com/questions/87922/ask-cli-does-not-use-region-setting-from-aws-confi.html</a>. The answer in that question implies that you can add a region field somewhere in one of the json files, but I can't figure out where. Any help would be appreciated.</p>
  
  <p>This is my ~/.ask/cli_config</p>
  
  <pre><code>{
    "profiles": {
      "default": {
        "aws_profile": "default",
        "token": {
          "access_token": "My_access_token",

  }

  <p>this is my ~/.aws/config</p>
  
  <pre><code>[default]

  <p>This is my skill.json, that i get when i call: "ask api get-skill -s skill_id > skill.json"</p>
