Currently router.isActive and routerLinkActive support only one option exact:boolean.

When exact = true, isActive will return true if:

• queryParams match exactly
• the url has the same url segments with all "path" equal
• matrix params are ignored

When exact = false, isActive will return true if:

• The queryParams of the containee is a subset of the queryParams of the container
• The url tree of the containee is a subtree of the url tree of the container
• Matrix params are ignored

We should replace the exact=true with a string type that supports more options:

• Include/exclude queryParams
• Include/exclude fragment
• Include/exclude matrix params
