Take a lock over the maintence client for etcd v3.
Modified the existing testMemberStatus UT to
- start 5 node etcd cluster
- stop 2 nodes
- spin 16 goroutines and check status of all the 5 members
- only the 2 stopped nodes should be unhealthy.
If the lock is removed the testMemberStatus UT will fail.
