Terraform

ENHANCEMENTS:

• backend/s3: Support role_arn in AWS configuration files (#22994)
• backend/remote: Remote backend will now ignore all .terraform/ (exclusive of .terraform/modules) and .git/ directories for uploads during remote plans/applies. You can exclude files from upload to TFC by adding a .terraformignore file to your configuration directory, more details at https://www.terraform.io/docs/backends/types/remote.html (#23105)

BUG FIXES:

• config: Clean up orphan modules in the presence of -target (#21313)
• config: Always evaluate whole resources rather than instances in expressions, so that invalid instance indexes can return a useful error rather than unknown (#22846)
• command/jsonplan: fix bug with missing nested modules planned_values output (#23092)
• command/show: Fix panic when the only resource instance is deposed (#23027)
• commands: When required root module variables are not provided and interactive input is disabled (-input=false), produce a proper "variable not defined" error rather than falling through to an internal assertion failure. (#23040)
• provisioner/puppet: fix bug when connection type was not set in config (#23057)
