Resolve "Set users limit to 0 for project and group creation"

What does this MR do?

In order to provide possibility to update all users that belongs to given group, its subgroups and projects belonging to the given group I created rake task. As described in #275962 my goal was to provide an easy way to update all users specified above with "Projects Limit" value set to 0 and "Can create groups" value set to false.

I decided to go with rake task as it allows to reuse this script for different clients.
