application error logs in cloudwatch and alarming on them based on thresholds.

Example

module "application_error_alarm" {
    source             = "github.com/Jareechang/tf-modules//cloudwatch/alarms/application-log-errors?ref=v1.0.12"
    evaluation_periods = "2"
    threshold          = "10"
    arn_suffix         = aws_lb.arn_suffix 
    project_id         = "my-test-project" 
    pattern            = "[Error]"
    log_group_name     = "my-log-group"
    metric_name        = "ApplicationErrorCount"
    metric_namespace   = "ECS-node-app-prod"
}
