To allow other checkpoint backends we extract a checkpoint interface which future checkpoints can implement. * Add checkpoint interface for custom checkpoints * Create RedisCheckpoint to implement checkpoint interface * Swap out hosie redis library for go-redis Minor changes * Allow configuration of Redis endpoint with env var `REDIS_URL` * Replace gvt with govendor
