…nfo when the address is not in cannonical form before this change when appeneding to the ClusterNetwork array if the cidr address is not in cannonical form the append happens outside the relevent scope and nil is appened, when a referance is made to the nil value the system segfaults.
…ct instead of the raw input from the master config file ParseNetworkInfo() will convert a given cidr address passed from the config file and transfrom it into canonical form. Use the converted cidr address returned from ParseNetworkInfo() to create the ClusterNetwork object.

Another reason for converting master.networkInfo.ClusterNetworks to []networkapi.ClusterNetworkEntry

Automatic merge from submit-queue. Fix crash with invalid serviceNetworkCIDR #17076 fixed the corresponding crash with clusterNetworkCIDR, but serviceNetworkCIDR had the same problem. Also, this slightly simplifies the previous fix.

Currently the system segfaults if passed a cidr that is not in canonical form, this was due to scoping issues in ParseNetworkInfo().
Also fix the creation of the clusterNetworkObject to use the converted form of the cidr address when creating the clusterNetwork object to conform to how the system used to function
