Giulio Fidente baf6eee501 Adds network/cidr mapping into a new service property
Makes it possible to resolve network subnets within a service
template; the data is transported into a new property ServiceData
wired into every service which hopefully is generic enough to
be extended in the future and transport more data.

Data can be consumed in service templates to set config values
which need to know what is the subnet where a deamon operates (for
example the Ceph Public vs Cluster network).

description: Configures sysctl net.ipv4.neigh.default.gc_thresh1 value.
This is the minimum number of entries to keep in the ARP
cache. The garbage collector will not run if there are
fewer than this number of entries in the cache.
type: number
NeighbourGcThreshold2:
default: 2048
description: Configures sysctl net.ipv4.neigh.default.gc_thresh2 value.
This is the soft maximum number of entries to keep in the
ARP cache. The garbage collector will allow the number of
entries to exceed this for 5 seconds before collection will
be performed.
type: number
NeighbourGcThreshold3:
default: 4096
description: Configures sysctl net.ipv4.neigh.default.gc_thresh3 value.
This is the hard maximum number of entries to keep in the
ARP cache. The garbage collector will always run if there
are more than this number of entries in the cache.
