cloudformation package should append profile name to deploy command

If the user uses the `--profile` flag during the package command, that flag should be echoed in the resulting `deploy` command that is issued. For example:
```
aws cloudformation package --template-file cloudformation/sam.yaml --output-template-file b.yaml --s3-bucket sam-bucket --s3-prefix sam --profile sam-app
```
should produce
```
Successfully packaged artifacts and wrote output template to file b.yaml.
Execute the following command to deploy the packaged template
aws cloudformation deploy --template-file b.yaml --profile sam-app --stack-name
```
