FALCON-1969 Provide server-side error details on CLI, if any
Here is a sample CLI output for comparison.
Before:
_[ambari-qa@sandbox falcon-0.10-SNAPSHOT]$ bin/falcon extension -submit -extensionName hdfs-mirroring -file /tmp/falcon-xml/hdfs-mirror-para.txt
Hadoop is installed, adding hadoop classpath to falcon classpath
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/usr/hdp/2.4.0.0-169/falcon-0.10-SNAPSHOT/client/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]

> Reporter: Ying Zheng
> Assignee: Ying Zheng

> Current CLI infrastructure only shows "Internal Server Error" when there is a server-side error. Should print error details on client side for the user to better understand the cause.
> See one example output from CLI and Falcon server log below. The CLI doesn't provide any detailed hints when the user forgets to add the required jobName property in the input. This information can only be found in Falcon server log. We should provide the hint "Missing extension property: jobClusterName" on CLI as well.
