Commit 0df613f5e3ece63ed21fe84db6044d06546e900d in impala's branch refs/heads/master from Lars Volker

IMPALA-8895: Expose daemon health endpoint
This change exposes the daemon health of an impalad via an HTTP endpoint
'/healthz'. If the server is healthy, this endpoint will return HTTP
code 200 (OK). If it is unhealthy, it will return 503 (Service
Unavailable). With this change, the endpoint is equivalent to the
'impala-server.ready' metric.
Testing: I added a test in test_web_pages.py and observed manually that
the endpoint returns 503 while starting up.
