Merge admin-user-action [f=1462387] [r=landscape-builder,free.ekanayaka,benji] [a=Данило Шеган] Create bootstrap action that creates an LDS account and adds an admin user
Introduce "bootstrap" action that takes "admin-name", "admin-email" and "admin-password" parameters and creates a "standalone" LDS account with the appropriate admin user.
At the moment, we are using 'schema --create-lds-account-only', though we should move to not using this in the future. This script doesn't report nicely if you've already called 'bootstrap' once.
