add --auto-answer CLI option

This patch:
- add --auto-answer CLI argument option
- bind it to a new Manager atomic bool
- force a answerCall to be called if an incoming call is created and
if the autoAnswer bool is true

Note: this option is not intended to be use with a client.
Use at your own risk.
