scylla_cluster: introduce `cluster.default_wait_*` properties

[fruch]

• moving the setting those default timeout into the cluster __init__ and a user of the cluster (i.e. dtest) can set those higher if needed.

• removed timeout argument from _start_scylla since no code in ccm or dtest were using it.

• reversed the order of wait_for_binary_proto with wait_other_notice since it was agree that wait_for_starting should happen first and the chances that after wait_for_binary_proto would end, wait_other_notice could finish much faster (current assumption is that no test is calling wait_other_notice=True while wait_for_binary_proto=False)

@bhalevy don't know if the best of interface, but it would allow for some test to set it higher before starting cluster/nodes
