Hello Michael Smith, Impala Public Jenkins,
I'd like you to reexamine a change. Please visit

to look at the new patch set (#4).
Change subject: IMPALA-11729: Speed up start-impala-cluster.py

IMPALA-11729: Speed up start-impala-cluster.py
The change reduces cluster startup time by 1-2 seconds. This also
makes custom cluster tests a bit quicker.
Most of the improvement is caused by removing unneeded sleep from
wait_for_catalog() - it also slept after successful connections,
while when the first coordinator is up, it is likely that all
others are also up, meaning 3*0.5s extra sleep in the dev cluster.
Other changes:
- wait_for_catalog is cleaned up and renamed to
wait_for_coordinator_services
- decreased some sleep intervals
- removed some non-informative logging
- wait for hs2/beeswax/webui ports to be open before trying
to actually connect to them to avoid extra logging from
failed Thrift/http connections
- reordered startup to first wait for coordinators to be up
then wait for num_known_live_backends in each impalad - this
reflects better what the cluster actually waits for (1st catalog
update before starting coordinator services)
