Azure DevOps - Terraform deployment - Run a validate and plan seperately

[lukemurraynz]

It would be great to be able to run a Terraform plan separately from the deployment - i.e. Terraform validates + plan, so you can run this without fear of accidentally deploying, especially useful during writing and testing the code, and knowing what changes it will make.

Could potentially add it to the validate sequence so that that pipeline can be run separately if required, or will this be included in the build pipeline.
