feat: complete puppet infrastructure (#29)

complete the implementation of puppet in kubernetes, taking many
features from the openvox helm chart and improving on them. changes from
helm are:
- using vault for storing secrets
- using g10k instead of r10k
- using a single shared g10k cronjob for all masters/compilers
- using a single shared /etc/puppetlabs/code directory (shared, cephfs)

changes:
- deploy puppet master and compiler servers with statefulset/deployment
- deploy puppetdb with postgresql backend, taking advantage of cnpg cluster and pooler
- deploy puppetboard
- all supporting configmaps, services, ingresses, and hpas
- added vaultstaticsecret for eyaml private keys
- configured secure mounting of eyaml keys at /var/lib/puppet/keys/
- updated base kustomization to include all 23 new puppet resource files
