profile options would not work for deploy:list

[st-h]

the profile option is not picked up when running deploy:list, as this config is never read and it seems like the profile option needs to be set before calling the S3 constructor (as it is done in the other ember-deploy-s3 plugins)

I additionally tried to add some log statements, however I was unable to use this.log. Even when passing it as a params to _list would show an error:

TypeError: Cannot read property 'logInfoColor' of undefined
TypeError: Cannot read property 'logInfoColor' of undefined
    at log (node_modules/ember-cli-deploy-plugin/index.js:76:34)

So, I went with console statements as I am unaware of the finer nodejs and ember-deploy details and I currently don't have any time to look into it. Will be happy to modify if someone can point me in the right direction.

Hey, just wanted to get back to this PR. Is there any issue, which prevents it from being merged?
