The suffix tfstate/tf-state is used as is instead of it being a variable.

The names of the storage and the resource group end up as prodtfstate and then results in an error because the storage name now is greater than 24 characters. See the steps below to reproduce. The config yaml required lines are as below

```
namespace: mlopsv2hez
postfix: 0918
location: westus
environment: prod
enable_aml_computecluster: true
```

Running the pipeline with the above configuration results in the following error. Mostly due to the name being 27 characters instead of it limiting to 24 characters.

> ERROR: (AccountNameInvalid) stmlopsv2hez0918prodtfstate is not a valid storage account name. Storage account name must be between 3 and 24 characters in length and use numbers and lower-case letters only.

> Code: AccountNameInvalid

>Message: stmlopsv2hez0918prodtfstate is not a valid storage account name. Storage account name must be between 3 and 24 characters in length and use numbers and lower-case letters only.

> ##[error]Script failed with exit code: 1

Potential fixes:
1. Use only the first 24 characters
2. Warn the user that the storage length is greater than 24 characters.
3. Remove the tf-state from the Terrafrom code. Check the lines below:
