Add staking extrinsics to the doracle pallet

[drbh]

• [ ] stake
• [ ] unstake

a person can signup to be a repeater. they have to submit more than a min amount. we need a way to verify they're in the pallet storage. they should be able to unstake.

tokens are native - (from balances pallet not assets pallet)

unstake

• your deposits
• your rewards

Stake

check if origin is allowed to stake

transfer HKO from staker to pallet

increment stake balance

add to repeaters if not in list

• to in N rounds (maybe 2-3)
• or implemented as a warming up period

Unstake

check if origin is staked

decrement stake amount

remove from repeater is stake is 0

unstake has a cool down period

• to deter staking supplying prices and unstaking in a short period of time

Continuation

• [ ] Implement rewards and slashing
• [ ] Configure static reward amount ( native currency )
• [ ] Rewards should calculate per round basis
• [ ] Come up with a formula for this
• [ ] Staking should lock for a specific epoch
• [ ] Change the repeaters structure for requirements

For Slashing consider last submitted time For rewards come up with a formula with block number transactions per block .......
