Martin Atkins 0e1fcb1bf7 main: Try to expand arguments starting with "@" from files on disk
This is a GCC-like behavior where we preproces the argument vector by
trying to treat any argument starting with "@" as a placeholder for
arguments loaded from a given filename.

As with GCC, if the remainder of the string cannot be used as a filename
to open and read, the original argument is retained literally. However,
if it _is_ possible to open and read a file of the given name then we
take that as sufficient evidence of the operator's intent to read from
that file and will fail with an error message if the file contents are not
acceptable syntax.

This uses the same upstream library as we've already been using for the
TF_CLI_ARGS... environment variables. Since main.go was quite overcrowded
with various different concerns, the handling of those environment
variables also moves into the new arguments.go file here, since the two
share an upstream dependency and both involve simplistic substitutions and
insertions into the argument vector. The observable behavior of the
environment variable handling should not be changed in any way by this
commit.

OpenTofu

OpenTofu is an OSS tool for building, changing, and versioning infrastructure safely and efficiently. OpenTofu can manage existing and popular service providers as well as custom in-house solutions.

The key features of OpenTofu are:

  • Infrastructure as Code: Infrastructure is described using a high-level configuration syntax. This allows a blueprint of your datacenter to be versioned and treated as you would any other code. Additionally, infrastructure can be shared and re-used.

  • Execution Plans: OpenTofu has a "planning" step where it generates an execution plan. The execution plan shows what OpenTofu will do when you call apply. This lets you avoid any surprises when OpenTofu manipulates infrastructure.

  • Resource Graph: OpenTofu builds a graph of all your resources, and parallelizes the creation and modification of any non-dependent resources. Because of this, OpenTofu builds infrastructure as efficiently as possible, and operators get insight into dependencies in their infrastructure.

  • Change Automation: Complex changesets can be applied to your infrastructure with minimal human interaction. With the previously mentioned execution plan and resource graph, you know exactly what OpenTofu will change and in what order, avoiding many possible human errors.
