fix(misconf): change default TLS values for the Azure storage account

[nikpivkin]

Description

Now the default minimum TLS value for storage account in Terraform is TLS1_2. But Azure ARM sets the default value depending on the deployment method. If the account is created via ARM, the MinimumTlsVersion property is not set by default and does not return a value until you explicitly set it.
