[Refactor build] Create deployment make command

Add a deploy command to the Makefile

• should deploy to dev
• should deploy to live

Add a build_and_deploy command to the Makefile, that bundles make build_live and make deploy, accepting a param to deploy either dev or live

The current script lives in https://github.com/IATI/IATI-Websites/blob/master/deployment/deploy_iati_standard.sh and imho does not make sense to be separate from this repository. The deploy logic should follow, roughly, the deploy part of this script and be kept separate from the build logic.

The new command should also allow us to deploy on the currently underused dev instances
