Retriable and non-retriable Pod failures for Jobs

This KEP extends Kubernetes to configure a job policy for handling pod failures. In particular, the extension allows determining some of pod failures as caused by infrastructure errors and to retry them without incrementing the counter towards backoffLimit. Additionally, the extension allows determining some pod failures as caused by software bugs and to terminate the associated job early. This is needed to save time and computational resources wasted due to unnecessary retries of containers destined to fail due to software bugs. <!-- This section is incredibly important for producing high-quality, user-focused documentation such as release notes or a development roadmap. It should be possible to collect this information before implementation begins, in order to avoid requiring implementors to split their attention between writing release notes and implementing the feature itself. KEP editors and SIG Docs should help to ensure that the tone and content of the Summary section is useful for a wide audience. A good summary is probably at least a paragraph in length. Both in this section and below, follow the guidelines of the [documentation style guide]. In particular, wrap lines to a reasonable length, to make it easier for reviewers to cite specific portions, and to minimize diff churn on updates.
