[calbera]

boonet branch is currently synced with v0.6.1. After merging this PR, future releases for the boonet network can be cut off of the boonet branch.

Effective changes are to validator set processing:

• The min stake (or EjectionBalance) is now set to 250k BERA
• The EffectiveBalanceIncrement (not the same as minimum deposit amount on the execution layer deposit contract) is now set to 10k BERA

@calbera question: should the Increment change too? I would say so.

[calbera]

done

LGTM, but I would change the EffectiveBalanceIncrement to a value that make sense given the new min and max
