To write documentation for FLIP-171 Async Sink Base. This will help sink
implementers get acquainted with the necessary information to write their
concrete sinks.

h2. Motivation
Apache Flink has a rich connector ecosystem that can persist data in various
destinations. Flink natively supports Apache Kafka, Amazon Kinesis Data
Streams, Elasticsearch, HBase, and many more destinations. Additional
connectors are maintained in Apache Bahir or directly on GitHub. The basic
functionality of these sinks is quite similar. They batch events according to
user defined buffering hints, sign requests and send them to the respective
endpoint, retry unsuccessful or throttled requests, and participate in
checkpointing. They primarily just differ in the way they interface with the
destination. Yet, all the above-mentioned sinks are developed and maintained
independently.
We hence propose to create a sink that abstracts away this common functionality
into a generic sink. Adding support for a new destination then just means
creating a lightweight shim that only implements the specific interfaces of the
destination using a client that supports async requests. Having a common
abstraction will reduce the effort required to maintain all these individual
sinks. It will also make it much easier and faster to create integrations with
additional destinations. Moreover, improvements or bug fixes to the core of the
sink will benefit all implementations that are based on it.
The design of the sink focusses on extensibility and a broad support of
destinations. The core of the sink is kept generic and free of any connector
specific dependencies. The sink is designed to participate in checkpointing to
provide at-least once semantics, but it is limited to destinations that provide
a client that supports async requests.
