Can disable ability and scope checking

[margarizaldi]

Changes

It can disable the ability and scope checking in Gate to not bother application that implement its own RBAC, especially for those having existing permissions with : character and takes advantage of can method such as spatie/permission.

I think this is important since:

• The Gate interception avoids us to use colon as permission name for our own rbac implementation
• using colon, such as view:user, create:post, etc is common practice
• Auth0 RBAC feature is optional after all

Also I believe that this PR won't introduce any breaking change.
