Allow configuring timeouts for aws_elasticsearch_domain

[amontalban]

Describe the Feature

Would be great to have create/update/delete timeouts for aws_elasticsearch_domain so upgrades do not timeout when applying them with Terraform.

Expected Behavior

Terraform should complete when doing upgrades from Elasticsearch 7.10 -> OpenSearch 1.3 (In certain cases this can take several minutes).

Use Case

We are in the process of upgrading several Elasticsearch clusters to OpenSearch, so running all this with Terraform would be ideal instead of using AWS Console.

Describe Ideal Solution

Ideally, timeouts should be configurable so each user can define the ones that are aligned to their case.
