This proposal takes its cue from the proposal on polkadot and is adapted to the times of kusama.
To gradually increase the number of slots for validators, I propose scheduling the increase over time.
The scheduled event mechanism aims to increase the number of validator slots steadily upon certain conditions:
An increase by 1 every era (6hs)
A repetition of the increase for 400 eras.
The proposal aims to avoid an abrupt increase in the number of validators on the network reaching the threshold of 1000 validators.
