Provide community feature to vote for locking the thread

Summary:

Some threads/discussions are going very longer in customer connect.

involving multiple people discussing, multiple different problems under one thread.

and we should have a feature to lock the threads, so that people will not have option to comment anymore,

and can ask new question if necessary.

Please provide a vote button, to vote for locking the thread.

or anything which can serve this.

many forums include this as a common feature.
