- some logger.info and logger.trace moved and added in order to improve the debug.
commented code not useful removed. Also the commented methods not useful has been removed: getDatabaseManagerAlgorithms, getParameters, getSubmitQueryResult, getSubmitQueryResultParsed, updateSubmitQueryResultParsed, removeResultParsed, updateSubmitQueryResultMap, removeResult git-svn-id: https://svn.d4science.research-infrastructures.eu/gcube/trunk/portlets/user/databases-manager-portlet@100945 82a268e6-3cf1-43bd-a215-b396298e98cf
