This motion is a bit of housekeeping and cleans the bounty proposal queue: closing 6 bounty proposals with no contextual information about their purpose. This proposal includes the closing of bounty proposals 3, 4, 5, 6, 7 and 8. Please note bounty proposers will lose their bond. 

Send a batch of dispatch calls.

May be called from any origin.

- `calls`: The calls to be dispatched from the same origin. The number of call must not
  exceed the constant: `batched_calls_limit` (available in constant metadata).

If origin is root then call are dispatch without checking origin filter. (This includes
bypassing `frame_system::Config::BaseCallFilter`).

# <weight>
- Complexity: O(C) where C is the number of calls to be batched.
# </weight>

This will return `Ok` in all circumstances. To determine the success of the batch, an
event is deposited. If a call failed and the batch was interrupted, then the
`BatchInterrupted` event is deposited, along with the number of successful calls made
and the error of the failed call. If all were successful, then the `BatchCompleted`
event is deposited.

- This motion is about closing bounty proposals.
- 6 bounty proposals will be closed.
- The proposals are numbers 3, 4, 5, 6, 7, and 8.
- The people who proposed the bounties will lose their bond.
- This is just housekeeping to clean up the bounty proposal queue.
