Description of problem:
When user creates a data role for a VDB, only read permission will be added to sysadmin. Thus, user cannot execute SYSADMIN.refreshMatView() by the lucking of the execute permission.

Version-Release number of selected component (if applicable):
JBDS 5.0.2.GA
Teiid Designer 7.7.4.v20130801-1634-H7-Final

Steps to Reproduce:
1. create a VDB
2. add a new Data Role and save
3. deploy it
4. send query to execute SYSADMIN.refreshMatView()
I modified $JBOSS_HOME/sample/quickstarts/eds_simple_jdbc_client/src/JDBCClient.java to send a query. as follows.

boolean result = statement.execute(sql);
System.out.println("result:"+result);

Actual results:

BUILD SUCCESSFUL
Total time: 47 seconds

Expected results:
User can edit permission for sysadmin by JBDS, so that SYSADMIN.refreshMatView() can be executed as expected

Additional info:
I tried to edit a vdb.xml directly, but there is no file under a teiid project
