Additionally to force-init option, we can use terraform providers and run terraform init if necessary, automatically. See this comment for more details - #299 (comment)

Not needed anymore. The current realization is superior to that

If there are no deps for t validate - it will fail in a fraction of a second, so no need to "force-init"
