UI should allow failing over inactive nodes when allowUnsafe is true

After changes in MB-45110 . We should allow selection of inactive(either inactiveAdded or inactiveFailed) nodes for multi-node failover during unsafe failover. 

Steps to Reproduce:
1. Create a 5 node cluster: n0 n1 n2 n3 n4
2. Stop-server on n4 and when the node becomes unresponsive, fail it over, but don't rebalance it out yet.

3. Now stop server on n2, n3 nodes.

Now it appears that we can't get the unresponsive nodes from steps 2 and 3 out of the cluster.
From the UI we can't quorum failover n2 and n3 as well as n4. 

In this case the UI should allow failover of node n4(inactive node) along with node n2 and n3(active nodes) when we get the message, "Cannot safely perform a failover at the moment".
