* Add kafka support to CLI (fbsql) This commit adds the ability to provide a `--kafka-config` command line argument referncing a toml file to configure kafka. * Move "Molecula Consumer" message to the logger; hide it in basic mode * Fold decimal(scale) into kafka.source-type * Build fbsql with cgo in docker for CI * Re-organize the fbsql kafka config and setup. Allow field config to use the table schema if no fields provided. * Display timestamp fields with format RFC3339Nano * remove kafkaRunner (no longer used) * Fix cli/batch test (and make sure it's not excluded from CI) The logic in our Makefile was exluding from tests any package with `/batch` in the package name. This excluded `/cli/batch`, which is not good. This commit changes the exclusion logic to include the `/v3` portion of the package name, so `/v3/batch`. * Rename Basic() to SetBasic()
