Kabum vacuum: rename file with yaml extension.

- add vacuum to filename to help users recognize potential matches.
- shorten the name
- standardise command and status following other supported vacuums
  in particular command names are for send_command actions rather than
  the UI, so use underscores rather than spaces. Some statuses are
  recognised specially when determining the state, so use those and
  make others consistent with them (lower case, single words)
- add duration class to cleaning time sensor
