Add generation of .csv file with test results

[mxprshn]

• If there is a .runsettings file with 'csvPath' test parameter (and optional runId), integration tests results and statistics are written (appended) to the corresponding .csv file

• Some TestSvm parameters can also be overridden in .runsettings file as follows:

<?xml version="1.0" encoding="utf-8"?>
<RunSettings>
  <TestRunParameters>
    <Parameter name="csvPath" value="D:\temp" />
    <Parameter name="runId" value="kek" />
    <Parameter name="searchStrategy" value="DFS" />
    <Parameter name="expectedCoverage" value="80" />
    <Parameter name="timeout" value="10" />
    <Parameter name="releaseBranches" value="false" />
</TestRunParameters>
</RunSettings>
