dhcp-all-interfaces: let NetworkManager doit.

Browse Source 
Override the default for DIB_DHCP_NETWORK_MANAGER_AUTO
to `true` on RHEL and CentOS release 8 and later.

The dhcp-all-interfaces element is configured to only
apply NetworkManager configuration. The service:
dhcp-all-interfaces will not be enabled. Not enabling the
service allows NetworkManager to do the interface auto-
configuration. In release 8 and later it should do this
just as good, or even better, compared to the
dhcp-all-interfaces.sh script.

On RHEL and CentOS 8 and later the *dhcp-all-interfaces* diskimage-builder
element is now configured to only apply NetworkManager configuration by
default. The *dhcp-all-interfaces* service will not be enabled.
To re-enable the *dhcp-all-interfaces* service, set
``DIB_DHCP_NETWORK_MANAGER_AUTO=false`` in the environment.
NetworkManager is quite capable to do automatic interface configuration.
NetworkManager will by default try to auto-configure any interface with
no configuration, it will use DHCP for IPv4 and Router Advertisements to
decide how to initialize IPv6.
