Allows manager command to see if IAX link is trunked and encrypted. Displays what kind of encryption is enabled as well.

Manager command "iaxpeers" now shows if a link is trunked and encrypted.  Instead of encryption saying simply "yes" or "no", it now displays what type of encryption is enabled and if keyrotation is on or not.  

(closes issue #14427)
