Bluetooth: Add conn info lifetime parameters to debugfs

This patch adds conn_info_min_age and conn_info_max_age parameters to
debugfs which determine lifetime of connection information. Actual
lifetime will be random value between min and max age.

Default values for min and max age are 1000ms and 3000ms respectively.
