Simon Willnauer e96fc3aa9f Add a flag to use minimim_master_nodes on the integ test cluster (#21173)
Setting `discovery.initial_state_timeout: 0s` to make `discovery.zen.minimum_master_nodes: N`
work reliably can cause issues in clusters that rely on state recovery once the cluster is available.
This change makes the use or `discovery.zen.minimum_master_nodes` optional for clusters where this behavior is desirable.
