`sui configure-domain` should create certificates in us-east-1

[alnorth]

I have my default region set as eu-west-2 (London). When I ran sui configure-domain it created the certificate in eu-west-2. However, when it came time to deploy I got the following error message:

21:50:46 | UPDATE_FAILED        | AWS::CloudFront::Distribution | ServerlessUI/Cloud...ion/CFDistribution
The specified SSL certificate doesn't exist, isn't in us-east-1 region, isn't valid, or doesn't include a valid certificate chain. (Service: AmazonCloudFront; Status Code: 400; Error Code: InvalidViewerC

The following resource(s) failed to update: [ServerlessUICloudfrontWebDistributionCFDistribution210665E2].

I believe this is because CloudFront requires certificates to be in eu-west-1.

When I created my own certificate in eu-west-1 and used that ARN in my config file then everything went smoothly.
