Add. BLF indication for call forward. (#2664)

Browse Source 
* Add. BLF indication for call forward.

To display general status of CallForward use blf like `forward+<extension>`
To display status for specific phone number use blf like `forward+<extension>/<number>`

* Fix. Escape variable in regex expression.

* Fix. Sync DND and CF blf.

* Add. `blf_subscribe` service which can handle all custom subscriptions.

To run for specific protocol it possible run as `luarun blf_subscribe.lua <PROTO>`
