Switching default profile breaks deployment

In multiple AWS account scenario, when we change the default profile environment variable `AWS_DEFAULT_PROFILE`, it breaks the deployment. It is because, `deployed.json` doesn't have profile attributes.

The existing structure of `deployed.json` can be changed to contain profile name attribute, like below:
```
{
"default": {
"dev": {
"api_handler_name": "",
"api_handler_arn": "",
...
},
"profile1": {
"dev": {
"api_handler_name": "",
"api_handler_arn": "",
...
}
}
}
```
