Update functest to fix failing tests

* MCE log plugin was failing becaue it wasn't enables
  * Updated a check for kernel version to match Fraser
    compute nodes on Apex
* RDT was failing when virtual compute nodes were used
  * Add check to detect whether compute node is a VM
  * Skip RDT when running in a VM
* Gnocchi metrics were failing
  * increase the wait time between checking metrics
* CSV checks were failing on Hugepages
  * functest was assuming that tests were running on
    a system with at least two NUMA nodes
  * Only check for metrics on node0 of the system
* Report was showing FAIL even if a test was not executed
  * Update the report output to show SKIP instead
