fix(model-server): change the model-server base image to RedHat

Description from #92

As discussed in a meeting yesterday, in order to reduce the number of vulnerable libraries in the dockerimage, I would suggest to switch for the RedHat-based OpenJDK image. The new model-server image was working fine for our use cases.

According to trivy, the openjdk:11 base image contains 323 vulnerable libs/software (UNKNOWN: 0, LOW: 123, MEDIUM: 61, HIGH: 109, CRITICAL: 30).

According to trivy, the RedHat-based base image contains 97 vulnerable libs/software (UNKNOWN: 0, LOW: 52, MEDIUM: 45, HIGH: 0, CRITICAL: 0).

Trivy was run on the latest modelix-model image (image ID 3d0f0ea586e4) to obtain this result. The used command was trivy image modelix/modelix-model:latest .
