Set up SKALE mirror in staging

Goal

Have SKALE mirror running in staging.

What needs to be done

• Config values need to be set up.
• Alter Cassandra table (do we want to alter views too?).
• Users will need to be decided/set up
• A sufficient supply of tokens and sFuel will need to be sent to the users configured for:
  • balance_sync_user_guid - Needs to be able to sync the entire network worth of offchain tokens.
  • sfuel_distributor_user_guid - Needs to have enough sFuel to distribute when requested by all custodial user wallets.
  • boost_escrow_user_guid - Needs enough balance to cover existing boosts in queue .
  • withdrawal_escrow_user_guid - Needs enough balance to cover existing withdrawals in the queue.
  • rewards_distributor_user_guid - Needs enough balance to cover Rewards
• Bootstapping development env docs should be followed as it's more or less the same process for production.
• Cronjob / runner needs deploying for the balance sync job.
• When running balance sync job - it WILL take a significant amount of time (possibly up to 24 hours).

Everything will need thorough testing, balance sync stream will need checking periodically.
