Add function to allow additional processes to be run

Maintenancetool does not allow updating install if running processes are
found from install directory. Only maintenancetool process was allowed,
otherwise the install failed with query to shut down processes. This
commit adds a function to extend the allowed processes to be
run, this is mandatory when running tests as test executable lies in the
install directory.
