Bucket schema management API?

Proposal:
A BucketSchemaApi to provide convenient access to the bucket schema management features.

Current behavior:

• While it is possible to create an "explicit" Bucket through the Java API, it is not possible to create a bucket schema

Desired behavior:
I want to be able to create a bucket schema for an explicit schema bucket

Alternatives considered:
The only way to do this currently is to directly use the InfluxDb HTTP API. Its quite awkward to be able to access almost all of the InfluxDb features through the client lib, but have to drop down to using a separate HTTP lib and JSON serialization/deserialization lib for my bespoke type for representing bucket schema.

Use case:
Bucket schema seem pretty important for ensuring bucket contents will always fulfill some basic content constraints. An implicit bucket can contain anything, so would require a ton of data validation for even the simplest use-case of bucket content consumption.

まず既存の Java bucket API と提案されている BucketSchemaApi を確認し、次に issue で参照されている InfluxDB HTTP API と比較します。クライアントが、個別の HTTP または JSON ライブラリを必要とせずに、明示的なスキーマを持つ bucket の bucket schema を作成できれば完了です。
