gsi_util: adding dump subcommand
'dump' command can dump information from given image, which could
be a image file, folder or device by adb.
Use $./gsi_util.py dump --help for the detail.
The patch also includes a "dump" framework, to implement some
dumpers to dump information. This patch also includes PropDumper to
dump information from property files, and XmlDumper to dump
information from XML files.
There is an initial dump info list in dump_info_list.py.
Use subcommand 'list_dump' could output the list.
Usually using Dumper is enough to dump information. dump.py is an
example to use Dumper.
