Instead of executing the custom script by calling system(), we should use the
functionality provided in base/process.h. This is preferred because it executes
the script with a well defined environment (only the PATH environment variable
is set, with a fixed value). Otherwise, all environment variables from clmna
will leak into the script. Any change in environment variables in clmna could
then be a non-backwards compatible change, if the user defined script depends
on the value of that variable. Another benefit of the base/process.h code is
that it lets us specify a time-out. We ought to have a time-out for the script
execution, and execute the script in a separate thread to avoid blocking the
main thread in clmna. This could be implemented in a similar way as for
executing the scale-out script in CLM.
