This implements one-pass removal oa a remote node from a mesh network
by issuing a node-reset command from config menu. The following actions
are performed:
- Config Node Reset message is sent to a remote node
- Upon either receiving Config Node Reset Status or response timeout,
node record is removed from configuration client's database and,
by calling DeleteRemoteNode() method on mesh.Management interface
node-delete command from the main menu is removed.
