increase beacon rounds durations and introduce jitter to reduce traffic spikes

[dshulyak]

beacon protocol total communication complexity is not bounded, and grows with the total number of activations registered in the epoch.

in latest epoch on mainnet with 16K activations traffic reached levels of hare (hare purple, beacon follow up votes orange).

while hare is bounded, and soon will be solved by hare3 - beacon grows is expected to continue.

• increase round to several hours (every round, except proposals, they are limited by threshold)
• add small jitter to at most half a round (e.g if round is 2h, jitter is between 0-60m)
