Support dev mode with TLS

[dzikowski]

To be checked if it is sufficient to provide TLS envs for the chaincode, like here:

https://hyperledger-fabric.readthedocs.io/en/release-2.2/cc_service.html

If TLS is enabled, the following additional options are required:

• CORE_CHAINCODE_TLS_CERT_FILE (–chaincode-tls-cert-file): path to a certificate
• CORE_CHAINCODE_TLS_KEY_FILE (–chaincode-tls-key-file): path to a private key
