- Restructured modules to use parameterized classes so that heira can be used
- IPs are automatically derived from interfaces which can be configured via heira
- Introduced network separation in backend / frontend net (but does not work yet)
- Removed loopback setup as this is not needed for production (need to introduce a parameter like "dev" or "virtual" to make it work again in vagrant)
- Set number of processes for storage server configuration statically to 8 (and not ::processorcount)
