This commit refactors the sqlserver, iotdb, elasticsearch, opents,
greptimedb, pulsar, tdengine, rabbitmq and s3 connectors to use the
`emqx_connector_info` behavior.
This is a trivial connector based on `emqx_s3` and simple action
that maps each incoming event into an S3 object upload. Due to
current `emqx_s3` limitation this bridge is compatible with
backends providing S3 API with path-style bucket access.
