Code Issues Proposed changes

Adds max-backoff for retries in Connection.

Browse Source 
The max-backoff concept prevents the backoff used in _retry to double infinitely (which in turn causes wait times of an hour or more between retries).

As per review, changed code to use min instead.

Fixes: bug #1183542
