Jenkins Recommendations

[Siphonophora]

We are looking for help adding platform specific recommendations (if any), screenshots, and examples for Jenkins which are similar to those here. https://github.com/spekt/junit.testlogger/blob/master/docs/gitlab-recommendation.md

When trying to submit JUnit files emitted by this logger to jenkins I found the folowing problems:

• Jenkins xUnit plugin doesn't support more than 3 decimal places for time attribute values
• This logger merge the standard-output stream in one tag at the testsuite level and doesn't split by testcase.
  -> this makes jenkins repeat the system-out content on each test case of the testsuite
