Aardvark-dns users must be able to specify `dns_servers` for containers at network level as well, so all the containers must inherit custom dns servers from their network if specified. What happens if both container's dns server and network's dns server are specified ? - In such case priority order is `network dns servers` and then container's `custom dns servers`. By default if nothing is specified resolution will happen from host's resolver Signed-off-by: Aditya R <arajan@redhat.com>

Configuration format
Aardvark-dns will read configuration files from a given directory.
Inside this directory there should be at least one config file. The name of the file equals the network name.
First line
The first line in the config must contain a comma separated list of listening ips for this network, usually the bridge ips. At least one ip must be given. Note: An optional second column of comma delimited domain name servers can be used at the network level. All containers on that network will inherit all the specified name servers instead of using the host's resolver.
[comma seperated ip4,ipv6 list][(optional)[space][comma seperated DNS servers]]
Container entries
All following lines must contain the dns entries in this format:
[containerID][space][comma sparated ipv4 list][space][comma separated ipv6 list][space][comma separated dns names][(optional)[space][comma seperated DNS servers]]
Aardvark-dns will reload all config files when receiving a SIGHUB signal.
