CLOUDSTACK-9872: Gather all S2S vpn statuses before outputting
The checkbatchs2svpn.sh VR script returns ("via echo") that status of each requested S2S VPN check one-at-a-time. If there is even a slight delay between VPN checks, the sshExecutor stops monitoring stdout and assumes it has all of the output.
When checking the management server logs, we see a request to check _X_ number of VPNs, but the response is occasionally less than _X_ number... The rest of the Cloudstack code assumes "isConnected" as false if the VPN is not included in the response.
We've noticed that if an account had more than 3 site-to-site VPNs, that there are many errors per day stating that a S2S VPN is down.
This is exacerbated by Issue CLOUDSTACK-9873, because that issues causes the S2S VPN check (and many others) to run twice as often as intended.
Example where a request was to check 4x S2S VPN connections, but only 3x responses were returned.
