Add aws.region to Installation page

[scyv]

When using the handy installation page of CloudConductor, you will get the error

" The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint. (Service: Amazon S3; Status Code: 301;"

whenn accessing a S3 Bucket package repository.

• Adding aws.region=eu-central-1 manually to the properties file resolved the issue.

=> Please add configuration of aws.region to the installation page AND into the example properties file.
