- Add setMetadataFile arg for setting/overriding metadata. This is more robust than passing it on the commandline. Input is a text file where each line corresponds to a metadata key/value and each line has the format <Key>=<Value>

-Add input format detection for csvConvert. If not specified, input format and compression will be used for output.
-Add -setMetadata key=value;... arg for overwriting metadata
