Add ability to build and deploy image locally using resin-cli
Using `resin build` a user can now build an image on their own docker
daemon. The daemon can be accessed via a local socket, a remote host and
a remote host over a TLS socket. Project type resolution is supported.
Nocache and tagging of images is also supported.

Using `resin deploy` a user can now deploy an image to their fleet. The
image can either be built by `resin-cli`, plain Docker, or from a remote
source.
