Terraform template_file remediation

[joshSpreston]

what

• All references to the deprecated hashicorp/template module have been replaced with the in-built function templatefile

why

• The hashicorp/template module has been retired by HashiCorp. It is no longer under development.
• Users with modern Macbook ARM processors, such as the M1, cannot utilize this module, as it has no arm64 build.

references

• closes Unable to initialize module on ARM #17

@Nuru we're trying to get M1 working and seem to be running into the same issue you came across in the past: hashicorp/terraform#26838 (comment)

I think this would be worked around by writing the remote config templates to disk using a local_file resource to write out the templates to disk and then pass them back into templatefile. any feedback on this approach?

@woz5999 have you been able to test out your PR branch?

The tests seem to have failed. Unfortunately you cannot use the local_file to write a file and then pass it to templatefile() because templatefile reads the file prior the terraform plan. There is no templatestring() function either.

Options

1. Use a forked version of the template provider that supports arm like gxben's fork.
2. Create a module that replaces the template string functionality and then use that module here
