This referendum is about changing the council and technical committee as follows:

- remove the member `6gkRvy75f8gngVgtbJ72WHWPf17xgFGHuE2h2vKce5cnBidw`
- add the member `6fFh66MVHosb9mBKfRhWxVTrBpmgnmE5XprTDRyEo42XjCHS`
- add the member `6f5hwqbCibJtUWGgXqbcGAAKBoBED9K3Suibp56kmcVJH5cS`

After this the council and technical committee will have the following six members:

- `6bgxxegcuBCYngSkJqp7bzgVZWd7brVrABEQetFq1R5dNa7T`
- `6cm5M5JVknj4NQdWpdayqwm92wzvSzjgE5SCRS7HM1EoauLm`
- `6eD6Ep2GxAsPrCLNMtPNEv2Nj9D3EzJsPzMBGz8R8JGgNXg3`
- `6f5hwqbCibJtUWGgXqbcGAAKBoBED9K3Suibp56kmcVJH5cS`
- `6fFh66MVHosb9mBKfRhWxVTrBpmgnmE5XprTDRyEo42XjCHS`
- `6fvm48ZH2NYvBasbFLm8r2t33K9tVL6y9Z14HWiaoAYr4WNi`


Send a batch of dispatch calls.

May be called from any origin except `None`.

- `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 the calls are dispatched without checking origin filter. (This
includes bypassing `frame_system::Config::BaseCallFilter`).

## Complexity
- O(C) where C is the number of calls to be batched.

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.

Problem Statement: The current council and technical committee membership needs to be changed.

Significance: This change will alter the composition of the council and technical committee.

Proposed Solution: Remove one member and add two new members to the council and technical committee.

Expected Outcomes: The council and technical committee will consist of six members with the new additions.
