> Container plugins are defined in {{/clusterprops.json:/plugin}} using a simple {{PluginMeta}} bean. This is sufficient for implementations that don't need any configuration except for the {{pathPrefix}} but insufficient for anything else that needs more configuration parameters.
> An example would be a {{CollectionsRepairEventListener}} plugin proposed in PR-1962, which needs parameters such as the list of collections, {{waitFor}}, maximum operations allowed, etc. to properly function.
> This issue proposes to extend the {{PluginMeta}} bean to allow a {{Map<String, Object>}} configuration parameters.
> There is an interface that we could potentially use ({{MapInitializedPlugin}} but it works only with {{String}} values. This is not optimal because it requires additional type-safety validation from the consumers. The existing {{PluginInfo}} / {{PluginInfoInitialized}} interface is too complex for this purpose.
