Fix an error when trying to load default variables

[jocgir]

I simply removed a lot of code that was handling error recovery. The new library we use returns the desired values even if there are error in the code. So, there is no need to try the whole retry process.

This pull request includes several changes to the util/terraform.go file, primarily aimed at simplifying the code and removing unnecessary functionality. The most important changes include the removal of unused imports, the elimination of redundant retry logic, and the deletion of the createTerraformVariablesTemporaryFolder function. Additionally, minor adjustments were made to the test cases in util/terraform_test.go.

Code simplification and cleanup:

• Removed unused imports path, regexp, and utils from util/terraform.go.
• Removed the reTfVariables regex and the isOverride function, as they are no longer needed. [1] [2]
• Simplified the loadDefaultValues function by removing the retry mechanism and associated temporary folder creation logic. [1] [2]

Test adjustments:

• Updated the TestLoadDefaultValues function in util/terraform_test.go to remove the test case for an invalid folder, which is no longer applicable.
