Handle secondary APN connect failures.
Without this we'd only try a secondary APN once and the stop silently, leaving
no APN connected.
Adds a second retry manager with configuration strings to do a more approriate
retry. Don't retry secondary apn forever.
On permanent failure or retry count hit, we send a Phone.REASON_APN_FAILED
disconnect status.
