Unable to manage Alert Channels at the Organization level

[afiune]

As a Lacework customer that is enrolled in a Lacework organization,
I want to be able to manage my Alert Channels at the Organization level,
So I can manage Alert Channels shared across Lacework sub-accounts.

Bug Description

Today, if any user try to manage an Alert Channel at the Organization level,
for example:

provider "lacework" {
  organization = true
}

resource "lacework_alert_channel_slack" "ops" {
  name = "ops critical alerts"
  slack_url = "https://hooks.slack.com/services/ABCD/12345/abcd1234"
}

The Lacework provider doesn't create (manage) this alert channel at the organization level,
but rather, at the sub-account level.

Proposal Solution

The problem we are facing is the fact that we are migrating the Lacework provider
from API v1 to API v2 and none of the Alert Channels have been migrated to v2.

APIv1 doesn't allow access to organization level data sets, so the solution is to migrate
all Alert channels to APIv2.
