[PR] KNOX-3030 - Make TopologyUtils.parse thread safe [knox]

["smolnar82 (via GitHub)" <gi...@apache.org>]

smolnar82 opened a new pull request, #901:
URL: https://github.com/apache/knox/pull/901

   ## What changes were proposed in this pull request?
   
   This change makes the `TopologyUtils.parse(...)` methods thread safe by synchronizing them. Another update is that occurrences of `SAXParseException` are handled separately and logged properly.
   
   ## How was this patch tested?
   
   Multiple automated tests were executed parallel to challenge Knox (more than 50 at a time). These tests were capable of reproducing the issue constantly. After repeating the same tests 3 times, we found no problems.
