Remove hardcoded internal PuppetDB URLs and site-specific wording so the
project is publishable as-is.
- backends have no default; require config file or PDBMUX_BACKENDS
- primary/prefer default to the first configured backend
- config init writes example.com placeholders
- Load no longer validates, so config init/version work unconfigured
- genericise README, package doc, help text and Dockerfile comment
Reports are immutable history, so a node that migrated has reports in the
old PuppetDB and the new one; serve the union rather than picking a single
owning backend as /facts does.
Re-apply order_by/limit/offset over the merged set and sum X-Records, since
each backend only orders and pages its own slice.
Split out from node-lookup PR #17 into its own repo. pdbmux presents a
single merged PuppetDB v4 query surface over the old (Consul) and new
(k8s) PuppetDBs during the VM to k8s migration, and is deployed in-cluster
via argocd-apps as a container image.
