Subject: [PATCH] Update set_fact.sh to support multiple network

Currently the role will fail to regather fact if $network_count > 1

That's because without the quotes echo will suppress the \n writing everything in one line. Thus wc -l will return `1`, confusing the file_content function that will lead to an incorrect json being produced
