* [JENKINS-34833] - Installation Wizard: Allow altering the list of succested plugins from update sites

In our company we provide a custom package of Jenkins, which provides a customized set of plugins (open-source and closed-source ones). These plugins come from the custom update site.

We would like to provide custom suggestions to users of our Jenkins packages when they install Jenkins. For such purpose we would like to make the plugin suggestions list overridable by UpdateSite extensions in Jenkins.
