Expose report filters inside change log tab

Expose "Filters" on the contact "Change Log" tab - including the new Log Type filter (but excluding the "Altered Contact" filter - since that's determined by the contact context). Changes to these filters affect only the current display in the contact tab. Default values are acquired from the Contact Summary report instance linked to the Change Log tabs.

At the moment just exposing filters inside tab, doesn't make reports working. We have to come up with a generalised change to make any report work inside tabs.
