Martin Atkins 0fb0a4b707 lint: DiscardedObjectConstructorAttrs
This generalizes the previously-added lint-like check for when an object
constructor is used to define an input variable and it contains a
definition for an attribute that isn't part of the target type, so that
now it also works for various nested structures that commonly arise in
real-world configurations.

Because this is now considerably more complicated I factored it out into
a new package called "lint" which could potentially grow to include other
similar "technically valid but probably a mistake" situations in future,
but for now it just introduced an opportunity to produce similar warning
messages for ignored attribute definitions in the default value for an
input variable.

It seems to me that there is actually no useful reason to include an
unexpected attribute definition in either of these two cases: that
attribute will never appear as part of any expression that any other part
of the configuration can use. Therefore I considered making these be
treated as errors rather than warnings, but turning something that was
previously valid into an error is risky so I'm suggesting that we start
with these as warnings and then consider upgrading them to errors in a
later release if we don't hear of anyone reporting a false-positive that
was _somehow_ actually useful. (I find that very unlikely, but still...)

OpenTofu

OpenSSF Best Practices

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.
