Currently, the port Management API listens on is hardcoded to 8080. This could cause port conflicts in certain deployments.
### Definition of Done
- [ ] All OSS/DSE Docker images are built with a port that is configurable via setting an environment variable
- [ ] The current hardcoded port of 8080 should be used if the environment variable is not set/present
- [ ] The README is updated to document the environment variable for setting the port.
