[QGIS-Developer] Adding a WCS Layer in QGIS makes multiple redundant calls.

[William Valencia]

I noticed something weird with QGIS. So when making an "Add WCS Layer" 
request with QGIS, I noticed that (After initial GetCapabilities and 
DescribeCoverage), multiple redundant calls to my WCS Server are made. 
The actual "Add" Button makes 12 calls to my WCS Server. It calls 1 
GetCapabilities, 1 DescribeCoverage, 4 GetCoverage and then repeats the 
last 6 calls for a total of 12 calls. I am unsure why QGIS makes 4 
GetCoverage calls in the first place, let alone the repeated last 6 
calls for the total of 12 calls. Anyone know why QGIS is doing this?

I am on a Mac running QGIS 2.18.9.
