When creating a BigQuery schema, it would be really nice to create a BigQuery schema from an avro schema, or json schema.

The command line tool seems to allow this; and the load command probably loads the schema from the avro file, and having this logic as a support class in the java api would add a lot of value.

Because honestly, I have an industry-standard schema. I don't really want to hand-code that same schema for BigQuery and I most certainly don't want to rely on manual load actions to initialise a schema.

My use case is more of a replication system. BigQuery is just one of the sinks.
I get my messages from Kafka, and can read them as byte[]. I also have the avro.Schema.
Ideally I would just give my bytes and the schema to BigQuery (the BigQuery client lib) and let that do the generic lifting.
