Apama Docker images moving to Amazon ECR

The Apama Docker images are now available at public.ecr.aws/apama, and can be viewed at ECR Public Gallery. Previously, they were available at softwareag/, and viewed at https://hub.docker.com/u/softwareag.

Within any Dockerfiles that use the Apama images, you will need to change FROM softwareag/<IMAGE>:<TAG> to FROM public.ecr.aws/apama/<IMAGE>:<TAG>.

The location of Apama within the image has been moved from /opt/softwareag to /opt/cumulocity. Existing images remain unchanged.
