Copy all users elasticsearch ALERTS to opensearch

[timckt]

Background

There are serval monitoring alert and destinations setting created by users and probably by click-ops and we need to migrate it to Opensearch.

We need to find a way to move the alert with terraform code.

Proposed user journey

Approach

Approach 1:

• Create a new centralised terraform code in cloud-platform-infrastructure repo to store the user side monitoring alert and destinations setting.
• If they would like to config/update those setting, they can raise ticket and we will help them to config.

Approach 2:

• We can create a module for Opensearch Alert and slack URL.
• One possible way to get the value for Opensearch Provider is to create data block with state file then to get those value.
