Add support for extension manager

[kaklakariada]

In order to support the extension mananger we need to add an extension that manages the Kinesis connector.

Steps to configure Kinesis connector

See user guide:

• Upload JAR to bucketfs ❌
• Create table with two special columns: KINESIS_SHARD_ID VARCHAR(2000), SHARD_SEQUENCE_NUMBER VARCHAR(2000) ❌
• Create three UDF scripts ✅
• Create connection with AWS credentials: ... IDENTIFIED BY 'AWS_ACCESS_KEY=<AWS_ACCESS_KEY>;AWS_SECRET_KEY=<AWS_SECRET_KEY>;AWS_SESSION_TOKEN=<AWS_SESSION_TOKEN>'; ❓
• Run import ❌

  IMPORT INTO <table_name>
  FROM SCRIPT KINESIS_CONSUMER WITH
  TABLE_NAME = '<table_name>'
  CONNECTION_NAME = 'KINESIS_CONNECTION'
  STREAM_NAME = '<stream_name>'
  REGION = '<region>';
