test_75_percent_availability fail against Ozone and S3 test environment
because test expects the string "SCAN HDFS" to be found in the profile.
Instead of it there's "SCAN OZONE" and "SCAN S3" for Ozone and S3 test
environment respectively. This patch fix the test by removing that
assertion from test_75_percent_availability. The remaining assertion is
enough to verify that FE planner and BE scheduler can see cluster
membership change.
