12 ... This resource holds private state (in suite variables),
13 ... which is generated once at Setup with ClusterManagement_Setup KW.
14 ... The state includes member indexes, IP addresses and Http (RequestsLibrary) sessions.
15 ... Cluster Keywords normally use member index, member list or nothing (all members) as argument.
18 ... odl-jolokia is assumed to be installed.
20 ... Keywords are ordered as follows:
22 ... - Shard state, leader and followers
23 ... - Entity Owner, candidates and successors
24 ... - Kill and Start Member
25 ... - Isolate and Rejoin Member
26 ... - Run Commands On Member
27 ... - REST requests and checks on Members
29 ... TODO: Unify capitalization of Leaders and Followers.
