Use long flag names

For readability, let's use the long flag names for the ESP options (https://cloud.google.com/endpoints/docs/openapi/specify-proxy-startup-options).

Note there's a comma after "SERVICE_CONFIG_ID". That doesn't look right to me, but I didn't want to change it without checking with somebody.
