As an advanced roadmap user I want to be able to easily exclude labels or components from a filter search so that I can narrow down my search results.

Use case:

Using labels as an example, but use case is true with other fields like components. We have many different labels tied to our issues. Sometimes, we would rather just exclude a certain label from the list, but that requires us to select all other labels first. The label filter doesn't have a 'select all' checkbox like status has. A select all box would allow for us to easily select all labels, then find the label we want to exclude.
