dm dust: convert documentation to ReST

2019-10-10T17:37:16Z

Convert the dm-dust documentation to ReST formatting, using literal blocks for all of the shell command, shell output, and log output examples. Add dm-dust to index.rst. Additionally, fix an annotation in the "querying for specific bad blocks" section, on the "queryblock ... not found in badblocklist" example, to properly state that the message appears when a given block is not found.
