Enable multi-worker setup

[Kailai-Wang]

Context

This ticket serves as the Epic issue for all multi-worker setup related issues.
When tackling the individual task, we should convert it to issues first, if not already.

Feel free to add more.

Known bugs/issues:
Some might be outdated / have a solution already, we need to double check it.

• Worker(NOT Primary) don't init state from genesis block on sidechain #1122
• Review the enclave registration process #1133
• check security when register enclave on parachain  #1163
• Double-check the consistency of STF execution status #1223
• Fork in sidechain block production #1524 (critical)
• Manual tests of removing the second worker during running #1525
• Attestation verification on Prod env #1542
• Top pool synchronisation in multi-worker setup integritee-network/worker#1397 (critical)
• Potential state mismatch caused by failed indirect trusted_call integritee-network/worker#1232

Other TODOs:

• releasing and deployment of packages (to multiple workers)
• Add CI test cases for multiple workers (2-3)
• Stress test and compare the result with single-worker
• Upgrade-worker practice for multiple workers
• Disconnection/resume tests for multiple workers
• Re-activate the time slot check in e1563e6
