Bug 1002401

Comments below copied from gerrit:

Initial draft.
Includes many other fixes to be able to actually use it.
Verified only on fedora 19:
engine-setup (chose to have it provision a local db, the default)
engine-backup --mode=backup --file=oeb4-local-db --log=oeb4.log
engine-cleanup
manually created a db in another host and opened access to it
Created a file "p1" with the remote's password engine-backup --mode=restore --file=oeb4-local-db --log=oeb4-restore1.log --db-host=didi-lap --db-pass=p1
Had to manually add ovirt services to firewalld's public zone and reload it
engine seems to work
engine-cleanup also works well, apart from:
[WARNING] Preserving '/etc/ovirt-engine/engine.conf.d/10-setup-database.conf' as changed since installation

Note: Passing --db-secured and/or --db-sec-validation does not change ENGINE_DB_URL, and it probably should. Not tested. It might be better to remove or disable these options for now.

*** Bug 1021448 has been marked as a duplicate of this bug. ***

Verified on RHEVM 3.3 IS21.

steps:
1.engine-setup
2.engine-backup --mode=backup --scope=db --file=/tmp/oeb4-local-db --log=/tmp/oeb4.log
3. created DB on remote host as per instructions on engine-backup --help
4. service ovirt-engine stop
5. engine-backup --mode=restore --scope=db --change-db-credentials --file=/tmp/oeb4-local-db --log=/tmp/oeb4-restore1.log --db-host=monique-vds05.tlv.redhat.com --db-port=5432 --db-user=engine --db-name=engine --db-password=engine
6. service ovirt-engine start; service httpd restart.
7. engine works fine, elements added to engine (Datacenter, cluster...) appear on remote database.

Found a bug : without http://gerrit.ovirt.org/21784 , engine-backup --mode=restore and without --change-db-credentials will empty 10-setup-database.conf and so will prevent the engine from starting.

reproduce steps:
1. engine-setup
2. create DC, Cluster, add hosts etc..
3. engine-backup --mode=backup --scope=all --file=/tmp/oeb4-local-db --log=/tmp/oeb4.log
4. engine-cleanup
5. drop database
6. create new database with same credentials as the previous one which was backed up
7. engine-backup --mode=resore --scope=all --file=/tmp/oeb4-local-db --log=/tmp/oeb4.log

result= engine works fine with all the elements installed at stage (2) in-tact.
