Add an option to ignore terraform_version in remote states

[nckbnv]

Current Terraform Version

$ terraform --version
Terraform v0.12.24

Use-cases

We have decoupled some of our terraform code in one of our projects from the rest (e.g. centrally create all VPCes, TGW etc) and then utilize the remote state in other accounts and states.

The terraform and provider versions are locked and usually bumped simultaneously, but sometimes you might end up in a situation in which the terraform version was updated on both ends, but you haven't made any changes with the new version, however your plan that relies on remote states will fail with:

Error: state snapshot was created by Terraform v0.12.24, which is newer than current v0.12.23; upgrade to Terraform v0.12.23 or greater to work with this state

Attempted Solutions

The only possible solution currently would be to decouple the state somehow, either with output to json or tools like consul as suggested in #15516 (comment), or not rely on remote states at all.

Proposal

I can see why this is a hard failure for state to which you are going to push changes, but as #15516 (comment) was made 2 years ago, I'm wondering whether it's now possible to make this a soft fail for remote states or add something like ignore_tags on provider level: e.g. ignore_remote_terraform_version
