For the login redirection feature, the current implementation works
only if a portal is redirected from an initial portal to a redirect
portal. However, the login redirection feature should work even if a
portal is redirected from one redirect portal to another redirect
portal.
A public portal group knows only a redirect portal and does not know
the portal group of the redirect portal.
Moreover, it is very likely that an initial portal and a redirect portal
exist in different SPDK iSCSI target applications.
To cover all these concerns, add an new iscsi_target_node_request_logout
RPC to request connections whose portal group tag match for the target
node.
To cover potential use cases, make the second parameter portal group
tag optional.
