* Auth: Add method `assertColumnRestrictions`
* ObjectSuggestions: Do not suggest protected variables
`assertColumnRestrictions` does not allow to use them
anymore, hence we should not suggest them in searches
as well to not to let the user run into an error by
accepting a suggestion. Though, when fetching values
as well, we still have to obfuscate, otherwise protected
vars won't show up in details anymore.
* Introduce Icinga\Module\Icingadb\Common\Model
Must be used as base for all models, to ensure
column restrictions are asserted on filters.
* Utilize `Icinga\Module\Icingadb\Common\Model` where applicable
* RedundancyGroupSummary:
- Columns are same as in DependencyNodeSummary. Column `redundancy_group.state.failed` excluded because not required here.
- Don't sort by default. Sorting the summary is not necessary and even fails for PostgreSQL as it would require adding the column to the GROUP BY clause.
- Introduce new method for(), to easily get the summary query for given group id. Adjust filter. The summary is always for parent (member).
