NIFI-2440 - Add 'file.lastModifiedTime' attribute to ListSFTP processor 

Added 'file.lastModifiedTime' attribute to ListFileTransfer, which is
the abstract class extended by ListSFTP.
String literal attribute names were replaced with static references to
attribute name constants in ListFile.
ListFileTransfer stores the 'file.lastModifiedTime' attribute in the
format specified in ListFile.FILE_MODIFY_DATE_ATTR_FORMAT

Updated WritesAttribute description for file last modify time attribute
to mirror the entry in ListFile
