terraform: remote state file exists check issue (#6296)

Browse source 
* remote state file exists check

In the official CLI implementation of Terraform, if the state file does not exist, a new one will be created, and there is no need to check that the state file already exists and with an error if file not exists.

```bash
# Test command
terraform apply -state test.tfstate. # if state file not exists ,terraform will create a new one
terraform destroy -state test1.tfstate  ### Terraform will not throw any error, the command will succeed execute, only report no resource has destroy
```
