Description of problem:
db user are not updated in second run of katello-configure

Version-Release number of selected component (if applicable):
katello-configure-1.1.10-1.git.93.01b51e4.el6.noarch

How reproducible:
alway

Steps to Reproduce:
1. run: katello-configure -b --db-name=katellodb --db-user=katello --db-password=olletak --deployment=katello
2. katello-configure -b --db-name=katellodb1 --db-user=katello1 --db-password=olletak1 --deployment=katello --reset-data=YES
3. select * from pg_user;
  
Actual results:
  usename  | usesysid | usecreatedb | usesuper | usecatupd |  passwd  | valuntil | useconfig 
-----------+----------+-------------+----------+-----------+----------+----------+-----------
 postgres  |       10 | t           | t        | t         | ******** |          | 
 katello   |    16384 | t           | f        | f         | ******** |          | 
...

Expected results:
I would expect user katello1 created, or if previously such user exist to modify its password or katello-configure to fail with error message.
