1306    Note that we have a chicken-and-egg problem during cluster init and upgrade. 
1307    This method checks whether the incoming connection comes from a master 
1308    candidate by comparing it to the master certificate map in the cluster 
1309    configuration. However, during cluster init and cluster upgrade there 
1310    are various RPC calls done to the master node itself, before the candidate 
1311    certificate list is established and the cluster configuration is written. 
1312    In this case, we cannot check against the master candidate map. 
1313   
1314    This problem is solved by checking whether the candidate map is empty. An 
1315    initialized 2.11 or higher cluster has at least one entry for the master 
1316    node in the candidate map. If the map is empty, we know that we are still 
1317    in the bootstrap/upgrade phase. In this case, we read the server certificate 
1318    digest and compare it to the incoming request. 
1319   
1320    This means that after an upgrade of Ganeti, the system continues to operate 
1321    like before, using server certificates only. After the client certificates 
1322    are generated with ``gnt-cluster renew-crypto --new-node-certificates``, 
1323    RPC communication is switched to using client certificates and the trick of 
1324    using server certificates does not work anymore.
