Referendum 71 was scheduled to be executed on block 3,200,000, and when it passed this was in already in the past. Submitting the same design as Ref 71 but as motion, since it was passed already via referenda, so we can fast track. 

This proposal will increase the validator count by 2 every 3600 blocks (1 era) 336 times (roughly over the course of 3 months).

At the end of this time period we will have a total of x+672 validators, where x is the number of validators slot once enactment of this proposal begins (in total 1172 if https://kusama.polkassembly.io/referendum/69 passes, of 1072 if it does not).

If at any point during enactment we see network stability or economics being harmed, we can cancel further increases using scheduler.cancel_named on the id this uses, 0x2b3325 (please ignore the fact this converts to +3% in utf8, I changed the parameters of the proposal based on advice and forgot to change the id).

 Schedule the currently externally-proposed majority-carries referendum to be tabled
 immediately. If there is no externally-proposed referendum currently, or if there is one
 but it is not a majority-carries referendum then it fails.

 The dispatch of this call must be `FastTrackOrigin`.

 - `proposal_hash`: The hash of the current external proposal.
 - `voting_period`: The period that is allowed for voting on this proposal. Increased to
   `FastTrackVotingPeriod` if too low.
 - `delay`: The number of block after voting has ended in approval and this should be
   enacted. This doesn't have a minimum amount.

 Emits `Started`.

- At the end of the time period, there will be a total of x+672 validators.
- If there are any issues with the network or economics, the increases can be canceled.
- Tl;dr: This proposal will add more validators to the network.
