History
Nadav Har'El 5de73f5480 test/cluster/auth_cluster: use CREATE ROLE IF NOT EXISTS to fix flaky test 
test_create_role_mixed_cluster calls servers_add(2) to bootstrap two old
nodes concurrently, then adds a new node before issuing CREATE ROLE.  The
concurrent bootstraps trigger the well-known Python driver bug
(scylladb/python-driver#317): two on_add notifications race in
update_created_pools, causing a second pool to be created for a host whose
pool was already established.  If CREATE ROLE is in-flight on the old pool
when it is closed, the driver retries on the new pool, executing the
statement twice.  The second execution fails with "Role ... already exists",
making the test flaky.

Fix by using CREATE ROLE IF NOT EXISTS.  This is safe because unique_name()
generates a timestamp+random suffix that is guaranteed to be unique; the
role can "already exist" only due to the driver double-execution bug, never
due to a real conflict.

This is the same workaround that has been applied many times elsewhere in
our test suite for exactly the same root cause:
- CREATE KEYSPACE was changed to CREATE KEYSPACE IF NOT EXISTS (scylladb#18368,
  later generalised in scylladb#22399 via new_test_keyspace helpers)
- DROP KEYSPACE was changed to DROP KEYSPACE IF EXISTS (scylladb#29487)

Fixes: SCYLLADB-1811

Closes scylladb/scylladb#29732

(cherry picked from commit 983eb5ab43)
