Question: what is the recommended approach to work with multi-module Gradle+Jib project

### Expected behavior
An easy way to work with individual modules/services in a multi-module Gradle+Jib project. For example a separate `skaffold.yaml` for each service with an easy way to share common configurations like namespace and Helm repo URL.

### Actual behavior
Skaffold fails with ` "gradle": executable file not found in $PATH` if executed from a module/service directory.
It works only if I execute Skaffold from the project's root directory with the full path to the configuration: `skaffold run -f service1/skaffold.yaml`. Helm release `valuesFiles` path resolved relative to the current directory and not `skaffold.yaml` file location requiring to configure it like this:
```yaml
deploy:
helm:
releases:
- name: services
valuesFiles:
- service1/values.yaml
```

Running `skaffold run -m service1` from the root project directory for a service configured in a Gradle module also results in `"gradle": executable file not found in $PATH` error.

The additional option to deploy separate services in a multi-module Gradle+Jib project is by creating a profile for each service which probably is not their intended purpose.
