Launching manual

[AurevoirXavier]

1. Perform a runtime upgrade on the solo chain to stop the chain
2. Export the solo chain state
3. Perform a runtime upgrade on the para chain to add the solo2para pallet and disable some pallet calls
4. Export the para chain state on a specific block height
5. Remove the assertions in parachain-system pallet and build the 2.0 node
6. Merge the chain states (shell, solo, para)
7. Send a solo2para call on para chain (the head data and code should be calculated from the merged state)
8. Launching the new chain base on the merged state
9. Correct the DMP/HRMP state Parachain system state check list #1083
10. Add the removed assertions in 5. back and perform a runtime upgrade for the new chain

Proposed a new version:

1. Perform a runtime upgrade on the para chain to add the solo2para pallet and disable some pallet calls, check there are sudo pallets and permissions
2. Perform a runtime upgrade on the solo chain to stop the chain
3. Export the solo chain state
4. Export the para chain state on a specific block height(record the block height)
5. Check/Remove the assertions in parachain-system pallet and build the 2.0 node(this should be included in the validation code?), Check/Set the DMP/HRMP data consistency in the meantime.
6. Merge the chain states (shell, solo, para), checking that the para id in shell is equal to production para id(or make sure the para id storage in genesis storage will be overwritten)
7. Upload to github release, and cross verify/review the 2.0 new header and validation codes by other devs
8. Send a solo2para call on para chain (the head data and code should be calculated from the merged state)
9. Launching the new chain base on the merged state
10. Check/Set the DMP/HRMP data correctly
11. Add the removed assertions in 7. back and perform a runtime upgrade for the new chain
