This PR is implementing the Proposal mentioned in #1726

In this PR,

  1. Added a new Interface
type Initializer interface {
	// GenerateDeployConfig generates Deploy Config for skaffold configuration.
	GenerateDeployConfig() latest.DeployConfig
	// GetImages fetches all the images defined in the manifest files.
	GetImages() []string
}

  1. Moved all the Kubectl deployer specific code to "github.com/GoogleContainerTools/skaffold/pkg/skaffold/initializer/kubectl" module and added tests.

  2. Moved all skaffold init processing from cmd/skaffold/app/cmd/init.go to pkg/skaffold/initializer/init.go and corresponding tests.
    In order to keep the diff minimum, i have not refactored a lot of code in to modules. I will refactor funcs like "resolveDockerfileImages" or "processCLIArtifacts" as appropriate when i add other intializers.

  3. Added tests for some utility functions.
