Check prereq instance communication network in 'SetParams'
Later, the logical unit for 'OpClusterSetParams' will be responsible
for creating the instance communication network in case it does not
exist. For now, it is important to check whether the network the user
is requesting to become assigned to instance communication has the
right configuration and otherwise warn about potential security risks.
- Add a new static method
'LUClusterSetParams._CheckInstanceCommunicationNetwork' which checks
if the user-supplied network is configured correctly and issues
security warnings otherwise. A correctly configured instance
communication network is link-local (i.e., 169.254.0.0/16 for IPv4
and fe80::/64 for IPv6), has no gateways, and has a specific MAC
prefix.
- Extend 'LUClusterSetParams.CheckPrereq' to call the above method to
check whether the user supplied network matches the intended
configuration.
