Adds Cloud-Native buildpacks project.toml file

This PR adds a Cloud-Native buildpacks project.toml file, which is similar to manifest.yml in CF. This allows us to set some project metadata and a list of files/folders to be excluded from build.

We are also setting 'BP_SPRING_CLOUD_BINDINGS_DISABLED=true' so that Spring Cloud Bindings are not enabled when building with Cloud-Native buildpacks. This is because Spring Music is set up to build from CloudFoundry bound Services & 'VCAP_SERVICES'. This reduces the chance of there being a conflict, like on Korifi where both 'VCAP_SERVICES' and K8s service bindings are present.
