Fixed arguments being passed to utils.Command for Command Notifier

[ralfonso-directnic]

The way the cmd string was being parsed result in utils.Command getting the following call
utils.Command("binary-to-call",[]string{"binary-to-call other args here"}, this properly removes the duplicate

After more investigation I moved the runCommand functionality to writing the command to a temp file and executing it. The existing method of parsing strings was inadequate when using quoted strings and was prone to failure

First of all: hi and thank you for you contribution :)

can you please give some more details on what impact the previous behaviour had to the outside? what do you have to set up (as a statping user) to get this to break?

As you might have seen in other conversations, 2 out of our 3 maintainers (including me) aren't familiar with go, so we kind of have to rely on your explaination and details here ^^

my first thought just from from what you've said so far: isn't writing to a tempfile just to execute it a bit hacky?

Addressed with #120
