app_queue: Add option for predial handlers on caller and callee channels

Browse Source 
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

When set the wrapuptime on the member is used instead of the wrapuptime
defined for the queue itself.
* Added predial handler support for caller and callee channels with the
B and b options respectively. This is similar to the predial support
in app_dial.
