remove mongodb that was installed via brew

# first check to see if mongo service is running. you can't delete any files until the service stops so perform a quick check.
launchctl list | grep mongo
# NOTE: the pipe | symbol means the commands on the right performs on the output from the left
# grep is a string search utility. `grep mongo` means search for the substring mongo
# use the unload command to end the mongo service. this is required to 'unlock' before removing the service.
# first look for the file to delete
