Ggeneralized the service wrapper script that does stdout+err redirection to a file

It's literally 3-4 dead simple lines of code

ServiceWrapper (must be made executable with something like chmod a+x ServiceWrapper)

#!/bin/bash -f
# -f: do not source .bashrc (for speed)
# Alain Andrieux, Platform

# Wrapper script for stdout/err redirection, service troubleshooting, etc...

# To use this wrapper instead of the service executable:
# 1) specify the startCmd of the service in the application profile as such:
# startCmd="${SOAM_DEPLOY_DIR}/ServiceWrapper MyServiceExecutable"
# 2) package this file along with the service executable
#
# To stop using this script, simply change the
# service startCmd in the app profile back to:
# startCmd="${SOAM_DEPLOY_DIR}/MyServiceExecutable"

serviceExeName=$1

shift

outputFile=$SOAM_HOME/work/$serviceExeName.$HOSTNAME.log

# The service deployment dir is in the PATH, so no need for absolute path
$serviceExeName $* >> $outputFile 2>&1

# Note:
# If the service executable name is ommitted or incorrect, the following kind of# error message will appear in the SIM log:
