## `namespaces.config` subsection
Example of `namespaces.json`.
Note that config values from `namespaces.json` can override config values for default namespaces
(value for which are fetched from regular config value e.g. [placement-policy](#placement_policy-section)).
To override config values for default namespaces use namespace names that are provided in `kludge.default_namespaces`.
