Description of problem:
When creating new datasource to load data from teiid, pre-filled field "Test Query" should contain test query but it contains "undefined".

File dataSourceRequiredScripts.jsp doesn't contain test query for Teiid.
Something like this should be added into line 28:
testQuerys[6]= "SELECT 1"; <%-- test query for Teiid --%>


Steps to Reproduce:
1. Log as administrator
2. Select administration > external connections > New DataSource > Custom DataSource
3. Select Teiid as DB Driver Class
