Add Java-/Typescript linting capabilities (#1636)

This change adds linting support for Java-/TypeScript projects based on the checkDefaultLint and checkUserLint steps from Cloud SDK Pipeline.

Following options are supported:

1. Define a linting script named ci-lint in the package.json file(s) of the project
2. Provide a configuration for ESLint as part of the project
3. If none of the above: ESLint is executed with a general purpose configuration.
