migrate dictionary `ipv6` into two simple lists - migrate dictionary `forward_zones` into a list * Restructure fastd configuration to define multiple instances easily - introduce mesh subdictionary `fastd` -

# Ansible role service-dhcpd
Diese Ansible role installiert und konfiguriert den isc dhcp daemon.
Wir nutzen diesen nur zur Verteilung von IPv4-Adressen.
- installiert isc-dhcp-server
- setzt interfaces in /etc/default/isc-dhcp-server
- schreibt dhcpd.conf
## Benötigte Variablen
- Dictionary `meshes`
´´´
meshes:
- id: xx
...
site_name: # string
site_code: # string
ipv4_network:
dnssl:
- $domain # string
iface_mtu: # integer
´´´
- Host Variable `magic`
- Host Variable `ipv4_dhcp_range`
## DHCP Range
In der Host-Variable `ipv4_dhcp_range` wird als Integer die Nummer des /22 Blocks aus `ipv4_network` definiert, welcher als DHCP Range verwendet werden soll. Dem Gateway Lotuswurzel ist die DHCP-Range 10.X.16.0-10.X.19.255 zugewiesen. Diese ist der 4. /22er Block, also wird in der Host-Variable für die Lotuswurzel `4` geschrieben.
