Apache Flink Table & SQL Connector for QuestDB

[Apache Flink](https://nightlies.apache.org/flink/flink-docs-master/docs/connectors/table/overview/) Sink for QuestDB via [ILP protocol](https://questdb.io/docs/develop/insert-data#influxdb-line-protocol). 

## Example

1. Start [local QuestDB](https://questdb.io/docs/get-started/docker)

2. Start [install and start Apache Flink](https://nightlies.apache.org/flink/flink-docs-master/docs/try-flink/local_installation/)

3. Start Apache Flink [SQL Console](https://nightlies.apache.org/flink/flink-docs-master/docs/dev/table/sqlclient/)

4. Create a dynamic table in Flink SQL Console:

```sql

CREATE TABLE questTable (a BIGINT NOT NULL, b STRING) WITH (

'connector'='questdb',

'host'='localhost',

'table'='flink_table'

)

```

5. Insert an item into the table created in the previous step:

```sql

insert into questTable (a, b) values (42, 'foobar');

```

6. Flink should create a table `flink_table` in QuestDB and eventually insert a new row into it.
