Add PV provisioner

This adds a new PV provisioner which works together with the
CSI Node driver to provide storage to workloads on Smalltown.
It talks to Kubernetes and listens for PVCs which need to be provisioned
and PVs which have been released and need to be deleted.

Is is implemented as a per-node agent where every node provisions the
volumes scheduled onto it by kube-scheduler.

Test Plan: Manually tested by running `bazel run //core/cmd/dbg -- kubectl create -f $PWD/pv-test.yml` and observing a provisioned PV that's attached to the pod. An example `test-pv.yml` is in P137.

Nexantic monorepo

This is the monorepo storing all of nexantic's internal projects and libraries.

Environment

We assume a Fedora host system provisioned using rW, and IntelliJ as the IDE.

For better reproducibility, all builds are executed in containers.

Usage

Spinning up: scripts/create_container.sh

Spinning down: scripts/destroy_container.sh

Running commands: scripts/run_in_container.sh <...>

Using bazel using a wrapper script: scripts/bin/bazel <...> (add to your local $PATH for convenience)

IntelliJ

This repository is compatible with the IntelliJ Bazel plugin. All commands run inside the container, and necessary paths are mapped into the container.

We check the entire .ijwb project directory into the repository, which requires everyone to use the latest version of both IntelliJ and the Bazel plugin, but eliminates manual setup steps.

The following steps are necessary:

  • Install Google's official Bazel plugin in IntelliJ.

  • Add the absolute path to your ~/.cache/bazel-nxt folder to your idea64.vmoptions (Help → Edit Custom VM Options) and restart IntelliJ:

    -Dbazel.bep.path=/home/leopold/.cache/bazel-nxt

  • Set "Bazel Binary Location" in Other Settings → Bazel Settings to the absolute path of scripts/bin/bazel. This is a wrapper that will execute Bazel inside the container.

  • Open the .ijwb folder as IntelliJ project.

  • Disable Vgo support for the project.

  • Run a non-incremental sync in IntelliJ

The plugin will automatically resolve paths for generated files.

If you do not use IntelliJ, you need to use the scripts/bazel_copy_generated_for_ide.sh script to copy files locally.
