Supported by vManager 17.10 and above only
In case of a need in adding the vsif environment variables, users can create a list of aliases and store them within a file. The job will 'source' that file prior of reading the vsif.
Note that this can also serve for any pre stage execution, not just for aliases.
Relative path is also supported (aka ~/doSomething.sh).
Script must be in bash or csh.

The file should be place into a directory with a read permission for the user who launches the regression.
In case this field is empty, this field is ignored
