[SPARK-21159][core] Don't try to connect to launcher in standalone cluster
mode.
Monitoring for standalone cluster mode is not implemented (see
SPARK-11033), but
the same scheduler implementation is used, and if it tries to connect to the
launcher it will fail. So fix the scheduler so it only tries that in client
mode;
cluster mode applications will be correctly launched and will work, but
monitoring
through the launcher handle will not be available.
Tested by running a cluster mode app with "SparkLauncher.startApplication".
