Description (What does it do?)

Fixes a warning from docker compose and removes travis related files.

Docker compose has been throwing warning about using the version in the config file. In addition I also noticed that we still have travis related things in the project. We have shifted to Github Actions for a long time now and shouldn't have any travis related things in project

How can this be tested?

• Check that there is no warning when you docker compose anything locally.
• Check that travis has now been removed from everywhere needed.
• All the checks should pass
• The project should build and run successfully
