dev: add Tiltfile for local development

[fmuyassarov]

This commit adds a Tiltfile to simplify local development with Tilt.

How to use it? To run balloons policy: tilt up balloons To run topology-aware policy: tilt up topology-aware

All it does is:

1. build the binary
2. create a container image and push to a temporary registry
3. deploy the policy Helm chart

I suppose this is ok, but the maintenance burden should be minimized. That is, go or docker build logic and parameterization should not be duplicated but used through make instead.

I have updated the binary build process to use the existing Makefile target. However, we can't replace the container image build process (docker_build) with a Makefile target. The docker_build is needed for instructing Tilt on how to build the image. Without it, Tilt won't be able to trigger dependent tasks, such as deploying Kubernetes manifests into a cluster.

That should be fine, the docker builds/Dockerfiles use the build system.

Do you think current state is okay to merge?
