Deploy on serverless service

[cblanquera]

Would be nice to have a command to deploy to a serverless stack with the following command.

$ incept deploy

Could have deploy configuration file to determine where and how to deploy.

{
  "service": "lambda",
  "key": "abc123",
  "secret": "GITHUB_KEY",
  "repo": "github.com/me/project.git"
}
