Easy build command to build all images for simnet, testnet or mainnet

Is your feature request related to a problem? Please describe.
Currently I have to manually check versions and see what I need in order to build all images I need for e.g. mainnet: https://github.com/ExchangeUnion/xud-docker#use-local-built-images

Describe the solution you'd like
tools/build mainnet (automatically pulling all correct versions from the template file)

The same way I should be able to use bash setup.sh -b local --dev --use-local-images all in order to not have to specify all images to be used from local. If an image that is needed is not present locally, it'll throw an error.
