backend: Cap number of "undeclared variable" warnings at four For users who in previous versions have relied on our lack of checking for whether variables are declared, they may previously have seen an overwhelming number of warnings when running Terraform v0.12. Here we cap that number at three specific warnings and then one general warning, so we can still give a specific source location for the first couple (for users who have genuinely made a typo) but summarize away a large number for those who are seeing this because they've not yet migrated to using environment variables.

backend/local: Handle interactive prompts for variables in UI layer During the 0.12 work we intended to move all of the variable value collection logic into the UI layer (command package and backend packages) and present them all together as a unified data structure to Terraform Core. However, we didn't quite succeed because the interactive prompts for unset required variables were still being handled _after_ calling into Terraform Core. Here we complete that earlier work by moving the interactive prompts for variables out into the UI layer too, thus allowing us to handle final validation of the variables all together in one place and do so in the UI layer where we have the most context still available about where all of these values are coming from. This allows us to fix a problem where previously disabling input with -input=false on the command line could cause Terraform Core to receive an incomplete set of variable values, and fail with a bad error message. As a consequence of this refactoring, the scope of terraform.Context.Input is now reduced to only gathering provider configuration arguments. Ideally that too would move into the UI layer somehow in a future commit, but that's a problem for another day.
