Detailed Description

Component that setup runtime configs based on fallbacks from file.

Static options:

Name	Description	Default value
updates-sink	name of the component derived from components::DynamicConfigUpdatesSinkBase to be used for storing fallback config	dynamic-config
fallback-path	a path to the fallback config	-
overrides-path	a path to the file containing overrides for a subset of fallback config parameters	-

If you use this component, you have to disable loading of other updaters (like DynamicConfigClientUpdater) as there must be only a single component that sets config values.

Static configuration example:

    dynamic-config-fallbacks:
      fallback-path: $runtime_config_path
