Top 5 Most Utilized Disks Read and Write Rates (over time) (BR10A)

Description of problem:
in 3 panels that show vms disks read and write rates (over time),
There is a bug in the queries - in some places in the query the maximum is taken instead of the average.
We want to display the average usage per point in time and not the maximum so this needs to be corrected.  

Version-Release number of selected component (if applicable):
4.4.4

How reproducible:
100%

Steps to Reproduce:
1.go to 'Trend Dashboard':

->Virtual Machines Resource Usage Dashboard:
2. go to 'Top 5 Most Utilized Disks - Read Rate (BR10C)' and 'Top 5 Most Utilized Disks - Write Rate (BR10C)'

->Virtual Machines Trend Dashboard:
2. go to 'Top 5 Most Utilized Disks Read and Write Rates (over time) (BR10A)'

Actual results:
The queries selects the MAX write or read rates in some places in the query

Expected results:
The queries selects the AVG write or read rates in all places in the query
