Fail a deployment before any resource creation for mismatches on cloud + location and cloud + tf environment

[glennmusa]

Benefit/Result/Outcome
Today deploy.sh and setup_ezdeploy.sh make use of defaults for AzureCloud to limit the number of arguments a user needs to provide to get started. However, those defaults aren't valid outside of AzureCloud and I shouldn't fail to deploy resources because I didn't know that those defaults were set for me and aren't valid.

Description
Provide a mechanism to check for valid Azure region and valid Terraform AzureRM environment setting.

Could use az account list-locations and terraform docs to source this information: https://registry.terraform.io/providers/hashicorp/azurerm/latest/docs#environment

Acceptance Criteria

• Provide a way to check for the current cloud + subscription settings to see if the region to be deployed into is available
• Provide a way to check for the current cloud that the Terraform environment is a match
• Do not deploy anything if the previous two are not valid
