Fix: Error response from daemon: all predefined address pools have been fully subnetted

[peaklabs-dev]

Note

• How do we make sure existing installs get this as well? This would require re-running the installation script and also restarting Docker - All containers would be offline shortly (not ideal) but there is no other way to fix this (at least I think so)
• This change is fully backward compatible, as all new containers will start using this range and old containers will stay on the old range of IPs.

Changes

• Introduced a much larger default docker network address pool - docker by default only allows 256 different /20 networks - well I ran out of networks today :).
• I used the IP address range {"base":"10.0.0.0/8","size":24} because this is what Docker Swarm uses, I use it for clear security network separation (in my setups) and it provides the most usable networks of any private IP range. It allows for up to 65,536 different /24 networks, each with 254 usable IP addresses.

Issues

• fix #3529
