record.get() function

record.get() is experimental and subject to change at any time.

record.get() returns a value from a record by key name or a default value if the key doesn’t exist in the record.

This is an interim solution for the exists operator’s limited use with records outside of a stream of tables. For more information, see influxdata/flux#4073.
