*
* AMF Node Class Implementation
*
* This file contains functions for handling AMF nodes. It can be
* viewed as the implementation of the AMF Node class (called NODE)
* as described in SAI-Overview-B.02.01. The SA Forum specification
* SAI-AIS-AMF-B.02.01 has been used as specification of the behaviour
* and is referred to as 'the spec' below.
*
* The functions in this file are responsible for:
* - controlling the instantiation of the SUs hosted on current node and
* controlling the assigning of workload to them when a node joins the
* cluster (cluster start is controlled by the Cluster Class)
* - controlling node level recovery and repair functions
* - implementing error escallation level 2 and 3 (paragraph 3.12.2.2 and
* 3.12.2.3 in the spec)
* - handling run time attributes of the AMF NODE; cached
* attributes are stored as variables and sent to the IMM service (future)
* upon the changes described in the specification
*
* The node class contains the following state machines:
* - administrative state machine (ADSM)
* - operational state machine (OPSM)
* - availability control state machine (ACSM)
*
* The administrative state machine will be implemented in the future.
*
* The operational state machine is primarily used to report status of the
* node.
*
* The availability control state machine is used for control purposes.
* ACSM contains three states of which two are composite.
* Being a composite state means that the state contains substates.
* ACSM states are:
* - REPAIR_NEEDED
* - IDLE (ESCALATION_LEVEL_0, ESCALATION_LEVEL_2 and ESCALATION_LEVEL_3)
* - MANAGING_HOSTED_SERVICE_UNITS (
* . FAILING_FAST (REBOOTING_NODE and ACTIVATING_STANDBY_NODE)
* . FAILING_GRACEFULLY (SWITCHING_OVER, FAILING_OVER and REBOOTING_NODE)
* . LEAVING_SPONTANEOUSLY (SWITCHING_OVER, FAILING_OVER and
* WAITING_FOR_NODE_TO_JOIN)
* . JOINING (STARTING_APPLICATIONS and ASSIGNING_WORKLOAD)
*
* REPAIR_NEEDED indicates the node needs a manual repair and this state will be
* maintained until the administrative command REPAIRED is entered (implemented
* in the future)
*
* IDLE is a composite state where no actions are actually performed
* and used only to remember the escallation level. Substate LEVEL_0 indicates
* no escallation. LEVEL_2 indicates that so many component restarts have been
* executed recently that a new component restart request will escalate
* to service unit restart action. Node will request a service unit restart
* from SU.
* LEVEL_3 will be entered if either there are too many service unit restarts
* been made or a component failover recovery action is requested. On level 3
* the recovery action performed is service unit failover (paragraph 3.12.1.3).
*
* FAILING_FAST state executes a node re-boot and waits for the node to join
* the cluster again. (not implemented)
*
* FAILING_GRACEFULLY state requests all SGs which have SUs hosted on current
* node to switch or failover according to the procedures described in
* paragraphs 3.12.1.3 before re-boot is executed. Then the confirmation is
* awaited from all concerned SGs and finally a node re-boot is executed as
* the repair action (see paragraph 2.12.1.4).
*
* LEAVING_SPONTANEOUSLY state handles the spontaneous leave of a node.
*
* JOINING state handles the start of a node in all cases except cluster start,
* which is handled by the CLUSTER class.

* 1.2 State Description
* =====================
* ESCALATION_LEVEL_X - Node is synchronized and idle (X = 0,2 or 3).
* JOINING_STARTING_APPLS - JOINING_STARTING_APPLICATIONS
* Node has ordered all applications to start its SUs
* hosted on current node and is now waiting for them
* to acknowledge that they have started.
* GRACEFULLY_FAILING_OVER - FAILING_GRACEFULLY_FAILING_OVER
* Node has ordered all SGs in the cluster to
* failover all SUs that are hosted on a specific
* node and waits for the SGs to confirm the
* failover is completed.
* GRACEFULLY_REBOOTING - FAILING_GRACEFULLY_REBOOTING_NODE
* Node has ordered reboot and waits for the rebooted
* node to join the cluster again.
* JOINING_ASSIGNING_WL - JOINING_ASSIGNING_WORKLOAD
* Node has ordered all applications to assign workload
* to all its SUs which currently have no workload and
* is now waiting for the applications to acknowledge.
*
* LEAVING_SP_FAILING_OVER - LEAVING_SPONTANEOUSLY_FAILING_OVER
* Node has received an event telling that this node
* has left the cluster and has ordered all service
* groups to failover those of its SUs that were
* hosted on current node.
*
* LEAVING_SP_WAIT_FOR_JOIN - LEAVING_SPONTANEOUSLY_WAITING_FOR_NODE_TO_JOIN
* Node is waiting for current node to join again.
*
* 1.3 Actions
* ===========
* A1 -

* A4 -
* A5 -
* A6 - [foreach application in cluster]start application
* A7 - [foreach application in cluster]assign workload to application
