[PROTON-1907] [electron/go] Memory leak seen when AtLeastOnce is used

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: proton-c-0.24.0
• Component/s: go-binding
• Environment: RHEL 7.5, Go 1.10.2

Description

The test program located here: 
   https://github.com/redhat-nfvpe/telemetry-bench
 
runs out of memory when AtLeastOnce is enabled instead of AtMostOnce.
The program tests throughput and connects to a 1.2 QDR.  The program
is generating about 20k messages per second and all messages are being
ack'd.  However, the program memory quickly hits several gigabytes and eventually
crashes due to a lack of memory.  When the the LinkOption is set 
to AtMostOnce, the program runs for hours with steady memory usage.  The problem also occurs on fedora with proton-c-0.22.
