Update Golang to 1.18. Update atmos to 1.4.22. Add ENV vars to data sources

[aknysh]

what

• Update Golang to 1.18
• Update atmos to 1.4.22
• Add ENV vars to data sources

why

• Use the latest Golang version, it offers many new features (including the any alias instead of interface{})
• Update to the latest version of atmos to use the latest features and improvements
• Add ENV vars to data sources - this will allow controlling the execution of atmos, utils provider and terraform using externally set ENV vars

locals {
  component   = "test/test-component-override"
  stack       = "tenant1-ue2-dev"
  tenant      = "tenant1"
  environment = "ue2"
  stage       = "dev"

  env = {
    ENVIRONMENT           = local.environment
    STAGE                 = local.stage
    ATMOS_CLI_CONFIG_PATH = "."
  }
}

data "utils_component_config" "example1" {
  component     = local.component
  stack         = local.stack
  ignore_errors = false
  env           = local.env
}

• In particular, the latest atmos version supports ATMOS_CLI_CONFIG_PATH ENV var to set the path to atmos.yaml CLI config file. This ENV var will allow using the monorepo pattern by loading a remote repo and pointing to its atmos.yaml using ATMOS_CLI_CONFIG_PATH ENV var

module "monorepo" {
  source = "git::ssh://[email protected]/ACME/infrastructure.git?ref=v0.0.1"
}

locals {
  monorepo_local_path  = "${path.module}/.terraform/modules/monorepo"
}

module "iam_roles" {
  source  = "git::ssh://[email protected]/ACME/infrastructure.git//components/terraform/account-map/modules/iam-roles?ref=v0.0.1"
  
  env = {
     ATMOS_CLI_CONFIG_PATH = "${path.module}/.terraform/modules/monorepo/rootfs/usr/local/etc/atmos"
  } 
  
  depends_on = [module.monorepo]
}
