IMPALA-7985: Port RemoteShutdown() to KRPC.
The :shutdown command is used to shutdown a remote server. The common
case is that a user specifies the impalad to shutdown by specifying a
host e.g. :shutdown('host100'). If a user has more than one impalad on a
remote host then the form :shutdown('<host>:<port>') can be used to
specify the port by which the impalad can be contacted. Prior to
IMPALA-7985 this port was the backend port, e.g.
:shutdown('host100:22000'). With IMPALA-7985 the port to use is the KRPC
port, e.g. :shutdown('host100:27000').
Shutdown is implemented by making an rpc call to the target impalad.
This changes the implementation of this call to use KRPC.
To aid the user in finding the KRPC port, the KRPC address is added to
the /backends section of the debug web page.
We attempt to detect the case where :shutdown is pointed at a thrift
port (like the backend port) and print an informative message.
Documentation of this change will be done in IMPALA-8098.
Further improvements to DoRpcWithRetry() will be done in IMPALA-8143.
For discussion of why it was chosen to implement this change in an
incompatible way, see comments in
https://issues.apache.org/jira/browse/IMPALA-7985.
TESTING
Ran all end-to-end tests.
Enhance the test for /backends in test_web_pages.py.
In test_restart_services.py add a call to the old backend port to the
test. Some expected error messages were changed in line with what KRPC
returns.
