[New Feature] List runtime variables / delete all runtime variables

I have checked the following:

• I've searched existing issues and found nothing related to my issue.

Describe the feature you want to add

I have a quite large collection which use the runtime variables a lot.

For the sake of run reproducible result I want to delete all runtime variables (set by bru.setVar function). I know that there is a bru.deletVar function which need the name of the variable to delete as parameter. I did not find a way to list all names of current runtime variables.

The ability of deleting all runtime variables will help in two situations:

1. When running folder or collection multiple time, the variables can be delete by a script.
2. If a collection consists of multiply folder, each top level folder can wipe all runtime variables. In this case the developer can be sure, that the result of a top level folder is not influenced by any preceding top level folder.

I also found the a function bru.hasVar() already exists. Unfortunately no documentation is available.

Mockups or Images of the feature

I want to have one of the following:

1. bru.deleteAllVars() - simply delete all runtime variables
2. bru.listVars() - return an array containing all names of runtime variables

The second solution enable the developer to achieve the first by building a loop over all variable names returned by bru.listVars() and delete each individually.

Hey @tho-gru-38 !

Thanks for describing your requirement in detail.
Yes, I think the bru.deleteAllVars() function makes sense.

@lohxt1 Can you take a look at this?
