Listen Docker registry port on internal network
Docker custom images are built on Dwellers,
but registry is hosted on Equatower.
Plan is to use IntraNought secondary NIC between the servers
for internal communication. Meanwhile, a GRE tunnel has
been prepared between the two servers.
The registry container is reconfigured to listen this IP.
Test Plan: Access to the registry from Dwellers
