Feature Request - Overwrite existing with Content Pack installation

In many cases it could be extremely helpful to be able to overwrite components (searches, rules, inputs, extractors, dashboard, etc.) during Content Pack installation if those components already exist in Graylog with the same name. This could avoid duplicates, or could reduce the amount of manual deletion work required if an administrator is attempting to make a mass change to a field name by creating a content pack, modifying the contents, and installing it back to the Graylog server. My recommendation is to not make this setting the default, but the capability to overwrite on Content Pack installation would be helpful.
