Gianluca Arbezzano d6a057c89d New tool to bump current_versions.sh automatically
This commit contains a new utility that helps to automate a version bump
for sandbox.

You can run this command to get the vibe of what it does.

```
$ go run cmd/bump-version/main.go -help
```

In order to try it out you can run this command form sandbox root. By
default it won't overwrite anything. It will print to stdout a new
version of the current_versions.sh file where all the images are
calculate cloning the various repositories

```
$ go run cmd/bump-version/main.go
```

If you want to overwrite the current_versions file you can use the flag
`-overwrite`.

More will come but for now, that's the PoC. Ideally this can be hooked
to CI/CD and run periodically, opening a PR that can be evaluated and
merged.
