Start local env even if ops-api.json config is missing

Generate ops-api.json config if the file is missing in cli `up` command: https://github.com/GalaChain/sdk/blob/main/chain-cli/src/commands/network-up/index.ts#L106

Probably the best way is to create and import a relevant function from chaincode root directory (`-d`), or call `/lib/cli.js get-contract-names`, as in https://github.com/GalaChain/sdk/blob/main/chain-cli/src/galachain-utils.ts#L147

Start in chain-cli/src/commands/network-up/index.ts around line 106 and inspect how the cli `up` command handles ops-api.json. Compare the suggested chaincode-root function approach with calling `/lib/cli.js get-contract-names` from chain-cli/src/galachain-utils.ts around line 147. Done means a missing ops-api.json is generated so the local environment can start.
