Migrate bare-metal module Terraform v0.11 to v0.12
* Replace v0.11 bracket type hints with Terraform v0.12 list expressions * Use expression syntax instead of interpolated strings, where suggested * Update bare-metal tutorial * Define `clc_snippets` type constraint map(list(string)) * Define Terraform and plugin version requirements in versions.tf * Require matchbox ~> 0.3.0 to support Terraform v0.12 * Require ct ~> 0.3.2 to support Terraform v0.12

|
||||
* Avoid unneeded rotations of Regular priority virtual machine scale sets
|
||||
* Azure only allows `eviction_policy` to be set for Low priority VMs. Supporting Low priority VMs meant when Regular VMs were used, each `terraform apply` rolled workers, to set eviction_policy to null.
|
||||
* Terraform v0.12 nullable variables fix the issue and plan does not produce a diff.
