Switch blockdev_getmirrorstatus_multi to per-node bodies

Even for a small 4-node node-group, this reduces the payload of this

serializer: Remove JSON indentation and dict key sorting

Serializing to JSON using “simplejson” is significantly slower when
indentation and/or sorting of dictionary keys is used. In simplejson 1.x

Change “node_info” RPC to accept multiple VGs/hypervisors

Keeping the node state up to date will require information from multiple

allows a single call to return all needed information. Existing users...

Change master IP address RPCs for external script

Change the master IP address RPC call chain to accept the

Show RPC calls from config in lock monitor

With this patch all RPC calls at runtime of masterd will show up in the
lock monitor. There is a chicken-and-egg issue with initializing the
configuration with a context since the lock manager, containing the
monitor, requires the configuration. This is worked around by setting...
