Command line tools

The kafka-storage.sh  tool will be updated in the following ways:

• The format  sub-command will produce meta.properties  in a new format described in the following section which includes two new properties directory.id and directory.ids. This sub-command already supports a formatting more than one log directory — by expecting a list of configured log.dirs  —  and "formatting" only the ones that need so.
• A new sub-command update-directories will be introduced to update the directory.id and directory.ids properties in meta.properties  in all log directories configured in the log.dirs  broker configuration. This command should be used when the configured log directories are already "formatted", e.g. when a log directory is removed from configuration.
