Python json.tool module errors

[sfchrisgleason]

So I'm using centos 7 and sometimes python dumps a bunch of error output along with the value causing zabbix to turn the item unsupported due to a type mismatch.

I redirected stderr with 2>/dev/null on each line in the bash script and it started working fine for me as I was getting sporadic results in the graphs.

I'm also using Zabbix 3.0 (I know it's old, planning on upgrading) but I back ported your template to 3.0 if you want it.
