Lint rule to enforce unnecessary this

[martin-braun]

Describe the rule you'd like to see implemented
I'm absolutely against avoiding the unnecessary usage of this, in-fact I'm the type of guy who wants to enforce it. The reason is simple: readability. I think it is very useful to immediately see if a variable comes from the function/global or class scope without inspecting it. Same goes to local and global functions. I'd like to enforce the usage of this whenever it is possible

I would call the rule enforce_unnecessary_this.

Thanks in advance.
