* 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()
