/**
 * This class is responsible for providing a docker interface with a remote (not running on localhost) docker host. It
 * can be configured by setting an environment variable {@value #DOCKER_HOST_SYSTEM_ENV }, like in the client. Or you
 * can specify the host and port on the command line like such:
 * -D{@value #DOCKER_HOST_PROPERTY}=[host] -D{@value #DOCKER_PORT_PROPERTY}=[port]
 * 
 * The provider defaults to {@value #TCP_PROTOCOL}://{@value #DEFAULT_DOCKER_HOST}:{@value #DEFAULT_DOCKER_PORT}
