Upgrade plan v0.8.1

[orenl-lava]

Upgrade plan from v0.7.1 to v0.8.1.

In v0.8.1 the StoreKey of module Projects changed from "projects" to "project". The store upgrade handler deletes the old storage and adds the new one. (Note that as of cosmos-sdk 0.45.11 the "Renamed" method for store upgrade did not work properly).

Disable the attempt for v0.8.0 (which left out the above change), because it led to a corrupt store state, and could not be easily re-upgraded to a working state.

How to test:

1. Checkout/compile lavad-v0.7.1, install the lavad binary
2. Start the server with ignite: ignite chain server
3. Run scripts/init_chain_commands.sh (should succeed as is)
4. Test the following commands:

curl http://127.0.0.1:3333/1/ --request POST --header "Content-Type: application/json" --data '{ "jsonrpc":"2.0", "method":"eth_blockNumber","params":[],"id":1}'
lavad query pairing clients ETH1
# notice the address of the staked client from the output, and use it below (replace the variable):
lavad query pairing get-pairing ETH1 $STAKED_CLIENT_ADDRESS

5. Submit proposal for upgrade:
   (note: adjust the "--upgrade-height 800" to use a block height not yet reached)

lavad tx gov submit-proposal software-upgrade v0.8.1 --title "v0.8.1" --upgrade-height 800 --upgrade-info '{"binaries":{"linux/amd64":"NONE"}}' --gas "auto" --from alice --description "lala1" --keyring-backend "test" --gas-prices "0.000000001ulava" --gas-adjustment "1.5" --deposit 10000000ulava --yes && lavad tx gov vote 5 yes -y --from alice --gas-adjustment "1.5" --gas "auto" --gas-prices "0.000000001ulava"

6. Wait until the chain reached the desired block height (800 in this example)
7. Kill all lavad: pkill lavad
8. Checkout/compile lavad-v0.8.1, install the lavad binary
9. Start the server again: lavad start
10. Confirm that the "get-pairing" works:

lavad query pairing get-pairing ETH1 $STAKED_CLIENT_ADDRESS

11. Re-run scripts/init_chain_commands.sh (the proposals should fail)
12. Re-run the tests again:

curl http://127.0.0.1:3333/1/ --request POST --header "Content-Type: application/json" --data '{ "jsonrpc":"2.0", "method":"eth_blockNumber","params":[],"id":1}'
lavad query pairing get-pairing ETH1 $STAKED_CLIENT_ADDRESS

13. Adjust the proposal id in the vote tx in scripts/init_subscription_commands.sh (should probably be 10,11,12 instead of 1, 2, 3)
14. Run scripts/init_subscription_commands.sh (should succeed as is)
15. Re-run the tests once more:

curl http://127.0.0.1:3333/1/ --request POST --header "Content-Type: application/json" --data '{ "jsonrpc":"2.0", "method":"eth_blockNumber","params":[],"id":1}'
lavad query pairing get-pairing ETH1 $STAKED_CLIENT_ADDRESS
