This turns the existing script into a proper sh_binary, and injects
dependencies (kubectl and jq) as deps into it.
This change also pulls in BUILDfiles for jq, and a dep (oniguruma) into
//third_party, and adds buildable external repositories for them.
The jq/oniguruma BUILDfiles are lifted from
https://github.com/attilaolah/bazel-tools/.

We're not using them for anything. Initially they were going to be used
for nixops, but nixops is not very good, so let's just drop them.
We still have a Nix dependency for clustercfg.py when provisioning
nodes, but rules_nix/nixpkgs in WORKSPACE were unrelated to that.

We still use etcd as the data store (and as such didn't set up k8s CRDs
for Calico), but that's okay for now.

Nixops requires nix_rules, which in turn requires a working nix
installation.
When we split tools/install.sh into tools/install.sh and
cluster/tools/install.sh [1], we accidentally made the latter always install
all cluster tools, including nixops - even if the install.sh script
detected that the system does not have Nix installed.
