// This test creates a scenario that large number of SS join the cluster, by excluding and including a random
// SS consistently for many times.
// this test would quit early in two scenarios:
// 1. QuitEarlyNoEligibleSSToExclude: All storage servers are running alongside with a TLog, thus we cannot
// exclude a SS, otherwise DB would be unavailable. (this is due to simulation uses UNSET process class)
// 1. QuitEarlyNoEligibleSSToExclude: All storage servers are running alongside with a TLog or LogRouter, thus we
// cannot exclude a SS, otherwise DB would be unavailable. (this is due to simulation uses UNSET process class)
// 2. QuitEarlyNotCompleteServerExclude: Sometimes it takes too long for a SS exclusion to finish(disappear from
// serverListKeys), there is a timeout_error when that happens, and we quit if it never succeeded( i.e.)
// It makes sense because the purpose of this test is to :
