Method such as a tickbox to change the behavior of 'Include Filter' against multibranch definition to become an exclude filter.

Example Usage Case

Project includes the following branches and want to exclude *-Private from multi-branch definition:

1.2.3-Rel

1.2.3-QA

1.2.3-Dev

1.2.3-Private

1.2.4-Rel

1.2.4-QA

1.2.4-Dev

1.2.4-Private

Workarounds at the moment would be:

• Use Perforce protections to hide *-Private from Jenkins user.
• Have multiple inclussionary expressions. For example '(.[1-9].*Rel)|(.[1-9].QA)|(.[1-9].*Dev)
