Subject: Add CPU and memory limits for apps

Adds --memory and --cpu flags to set systemd resource limits:
  ship --binary ./app --memory 512M --cpu 100%

Also adds config update mode - use --name without --binary to
update an existing app's config without redeploying the binary:
  ship --name myapp --cpu 50%
  ship --name myapp --memory 256M --env DEBUG=true

Limits are stored in state and preserved on redeploy.
