idleness and need to be reconnected before use.

This caches the output of the following methods:

* Repository#empty?
* Repository#has_visible_content?
* Repository#root_ref

The cache for Repository#has_visible_content? is flushed whenever a
commit is pushed to a new branch or an existing branch is removed.
The cache for Repository#root_ref is only flushed whenever a user
changes the default branch of a project. The cache for Repository#empty?
is never explicitly flushed as there's no need for it.

Error: A copy of Gitlab::CurrentSettings has been removed from the module tree but is still active

Fixes #3071.

The current commands shown don't work in Command Line, or PowerShell.

This commit provides commands that will work for both the Command Line, and PowerShell.
