[3.x][Filesystem] Provide an additional argument for tenant name path (…

…archtechx#817)

* Let the user pass the tenant suffix by %tenant%

In this PR we let the user pass an additional parameter using `%tenant%` so the user can additionally pass the folder corresponding to each tenant.
This is my proposal, because if I try to use %storage_path% within Linux, I get the full path to the project when I use Google Cloud Storage

* Missing missing updates

Moving from $subject to $root when %storage_path% has been replaced
