Resource datadog_monitor - Tags always change

[shaulishaked]

Hi there,

Terraform Version

Terraform v0.11.13

• provider.datadog v1.8.0

Affected Resource(s)

Tags in datadog_monitor

Expected Behavior

When no changes are done in Terraform datadog_monitor configuration,
terraform apply command should return empty changes.

Actual Behavior

Terraform will perform changes - changing the order of the tags in the monitors in which there are more than 1 tag.

Steps to Reproduce

1. Create a monitor with multiple tags = []. For example: tags = ["this", "is", "a", "test"]
2. Run terraform apply to create the monitor.
3. Run terraform apply to see that there are Terraform changes:
   Terraform will perform the following actions:

~ module.<module_name>.datadog_monitor.<monitor_name>
tags.#: "this" => "is"
tags.2: "a" => "test"
tags.3: "is" => "a"
tags.4: "test" => "this"
