app_queue: Add option for predial handlers on caller and callee channels
Add predial handler support to app_queue. app_dial (ASTERISK_19548) and app_originate (ASTERISK_26587) have the ability to execute predial handlers on caller and callee channels. This patch adds predial handlers to app_queue and uses the same options as Dial and Originate (b and B). The caller routine gets executed when the caller first enters the queue. The callee routine gets executed for each queue member when they are about to be called. ASTERISK-27912 Change-Id: I5acf5c32587ee008658d12e8a8049eb8fa4d0f24
