feat: Adds prefix to projects and folder name

[amandakarina]

Hey folks,

This pull request closes #270 issue and closes #275 issue.

Could you, please, take a look?

Thanks!

When creating a project, setting the variable to empty:

project_prefix       = ""

will result in the error: Project ID can have lowercase letters, digits or hyphens and must start with a lowercase letter.

should we add a warning in the variable description saying that the value must not be empty ?

OR do we need to write some logic around it?

@daniel-cit I think its okay to keep it as is. The error surfaced is clear, easy to recover from and we do define a default. Perhaps it does make sense to add some language in the variable description, so that its clear in the docs.

@amandakarina looking at the build output, it seems like in 4-projects we are still using prj for testing. Could PTAL
