Added support for the Amazon Web Services (AWS) me-central-1 Middle East region

aws-me-central-1 has been added as the second Amazon Web Services (AWS) Middle East (ME) region where Aiven services are supported (on top of the existing aws-me-south-1). Now you can select the new aws-me-central-1 region when creating a service or as a target region when migrating your service. More flexibility in selecting cloud regions means better cloud computing experience, higher resources availability, and improved data security. For the full list of the supported regions, see List of available cloud regions.
