Another panic was found with this resource. IT essentially was causing a
panic when no certificates were found. This was due to the casting of
status to []string
There are times when there are no statuses passed in. Made the error
message a lot more generic now rather than having something like this
```
No certificate with statuses [] for domain mytestdomain.com found in this region.
```
This now becomes:
```
No certificate for domain mytestdomain.com found in this region.
```
Also, added a test to show that the panic is gone
```
% make testacc TEST=./builtin/providers/aws TESTARGS='-run=TestAccAwsAcmCertificateDataSource_'

Fixes#9989
When passing a list of statuses to the acm_certificate data source, we
were trying to cast a schema.TypeList directly to []string
We need to do it via an []interface{} and then cast to string when
ranging over the results. Without this, we get a panic
Use this data source to get the ARN of a certificate in AWS Certificate
Manager (ACM). The process of requesting and verifying a certificate in ACM
requires some manual steps, which means that Terraform cannot automate the
creation of ACM certificates. But using this data source, you can reference
them by domain without having to hard code the ARNs as input.
The acceptance test included requires an ACM certificate be pre-created
in and information about it passed in via environment variables. It's a
bit sad but there's really no other way to do it.
