feat(cosmwasm)!: change non-governance scripts to use subcommands

[eguajardo]

Available subcommands:

• upload: Uploads wasm file and saves codeId to lastUploadedCodeId in config

  e.g.: node cosmwasm/deploy-contract.js upload -m "$MNEMONIC" -a "../artifacts/" -c "Router" --instantiate2 -e devnet -y --salt "$ROUTER_SALT"

• instantiate: Instantiates a contract, it gets the codeId by order of priority from:

  1. Value of --codeId option
  2. From the network by comparing code hash when using --fetchCodeId option
  3. Value of previously saved lastUploadedCodeId in config

  e.g.: node cosmwasm/deploy-contract.js instantiate -m "$MNEMONIC" -c "Router" --instantiate2 -e devnet --admin "$ADMIN_ADDR" -y --salt "$ROUTER_SALT"

• upload-instantiate: Both uploads and then instantiates a contract using the code Id that was just created. It doesn't accept --codeId nor --fetchCodeId options

  e.g.: node cosmwasm/deploy-contract.js upload-instantiate -m "$MNEMONIC" -a "../artifacts/" -c "ServiceRegistry" -e devnet --admin "$ADMIN_ADDR" -y --instantiate2 --salt "$SALT"
