"Reserved prefixes" rule

Summary of the new feature

A while ago, the PowerShell extension had an issue open on it because

Get-Help Get-AdUser -Online

and

Get-Help Get-AdFoo -Online

(note, Foo is used to make it obvious and I forget what the actual noun was)

Were not giving the same result...

As it turned out, its because Get-AdFoo was from a module from the Gallery... Where Get-AdUser comes from the inbox Active Directory module.

Personally, I think it's quite dodgy to overload such a crucial prefix like Ad and we should warn users that certain prefixes are used already in very critical modules.

Proposed technical implementation details (optional)

A rule that gives a warning that says "you probably shouldn't use this prefix because it's already used by X"

Or something to that effect.
