IMPALA-10224: Add startup flag not to expose debug web url to clients
This patch introduces a new startup flag
--ping_expose_webserver_url (true by default) to control whether
PingImpalaService, PingImpalaHS2Service RPC calls should expose
the debug web url to the client or not.
This is necessary as the debug web UI is not something that
end-users will necessarily have access to.
If the flag is set to false, the RPC calls will return an empty
string instead of the real url signalling that the debug web ui
is not available.
Note that if the webserver is disabled (--enable_webserver flag
is set to false) the RPC calls will behave the same and return an
empty string for the url.
