Start to send data to Snowflake too (#20698)

This PR adds support for sending telemetry events to AWS Kinesis.

In our AWS account we now have three new things:
* The [Kinesis data
stream](https://us-east-1.console.aws.amazon.com/kinesis/home?region=us-east-1#/streams/details/zed-telemetry/monitoring)
that we will actually write to.
* A [Firehose for
Axiom](https://us-east-1.console.aws.amazon.com/firehose/home?region=us-east-1#/details/telemetry-to-axiom/monitoring)
that sends events from that stream to Axiom for ad-hoc queries over
recent data.
* A [Firehose for
Snowflake](https://us-east-1.console.aws.amazon.com/firehose/home?region=us-east-1#/details/telemetry-to-snowflake/monitoring)
that sends events from that stream to Snowflake for long-term retention.
This Firehose also backs up data into an S3 bucket in case we want to
change how the system works in the future.

In a follow-up PR, we'll add support for ad-hoc telemetry events; and
slowly move away from the current Clickhouse defined schemas; though we
won't move off click house until we have what we need in Snowflake.
