ASO test on Couch with EPH + ZFS/ZIL

see: https://cern.service-now.com/service-portal/view-request.do?n=RQF0557816

Only look after ZFS cache was reconfigured to avoid latency in writing (sync = default)

kibana plots of ASO metrics June 1st to June 20th. For the test and for the production instance. Horizontal scale is same for all plots. Vertical scale is the same for the "green" plot (i.e. completed xfers, which is somehow tracking # of injected). Vertical scale for Current/New is adjusted to what the plot has, and for the test instance the plot appears twice with different scales to show all data.
