Rationale for this change
As pointed out by @alamb https://github.com/influxdata/influxdb_iox/pull/4743/files/5fccaab1f94f7e5b8b69ab35ea11c151cb1b8a2d#r885642739 the UX of getting the parquet schema from a ParquetFileArrowReader is not great.
What changes are included in this PR?
Adds a parquet_schema member function that returns the schema.
It also deprecates the get_metadata function, as it doesn't need a mutable reference nor to return a clone, and replaces it with a
metadata
function that is consistent with the equivalent method on FileReader.Are there any user-facing changes?
A function is deprecated
