`GrowShrinkClusterNemesis` fails when current number of nodes is less the initial number of nodes

7

`_grow_cluster` allways adds a fixed number of nodes (`nemesis_add_node_cnt`). but `_shrink_cluster` removes a relative number of nodes `decommission_nodes_number = min(cur_num_nodes_in_dc - initial_db_size, add_nodes_number)` In this example, https://argus.scylladb.com/tests/scylla-cluster-tests/0b0e042d-60a7-4dad-832d-4e38f2e5a5e9, when the nemesis...
