Wido den Hollander e894658f8c kvm: Allow Link Local Cidr (cloud0 interface) to be configured (#3500)
There are certain scenarios where the 169.254.0.0/16 subnet is used for different
purposes then CloudStack on a hypervisor.

Once of such scenarios is a BGP+EVPN+VXLAN setup using BGP Unnumbered where the
169.254.0.1 address is used by Frr/Zebra BGP routing to send traffic to the
neighboring router.

The following settings can be changed in the agent.properties (default values added):

control.cidr=169.254.0.0/16

Make sure the global setting 'control.cidr' matches the values defined in the agent.propeties!

In the future the mgmt server can send this parameter to a KVM Agent on startup, but at the moment
this framework is not in place and thus these values can't be send to the Agent in a proper manner.
