SqlFailoverClusterNode: New resource proposal

[johlju]

Resource proposal

A class-based SqlFailoverClusterNode resource would manage adding or removing nodes in a SQL Server FCI, and completing cluster configuration steps. It would use Add-SqlDscNode, Remove-SqlDscNode, and Complete-SqlDscFailoverCluster.

Proposed properties

Property	Type qualifier	Data type	Description	Default value	Allowed values
Ensure	Key	String	Whether the node should be Present or Absent in the FCI	Present	Present, Absent
NodeName	Key	String	Name of the cluster node	None	Any valid node name
InstanceName	Key	String	The SQL Server instance name	None	Any valid instance name
ClusterGroup	Write	String	Cluster group name	None	Any valid group name
ClusterIPAddress	Write	String[]	IP addresses for the cluster	None	Any valid IP address list

Special considerations or limitations

Should ensure changes do not disrupt cluster availability, support coordination with setup and cluster resources, and handle permission and network requirements for cluster operations.
