Description of problem:
Given an application ssh key content is updated in mongo, which makes the ssh key inconsistent with the gear ssh key on node, when oo-admin-chk -l 1 is executed, the mismatched ssh key is not detected.

Version-Release number of selected component (if applicable):
On fork_ami_origin_broker_admin-chk_960

How reproducible:
Always

Steps to Reproduce:
1. Create a scalable application
2. Update the app_ssh_keys with rockmongo interface, change the content of the app sshkey
3. Verify that the mongo ssh key content is different gear ssh key
4. oo-admin-chk

Actual results:
After step 3: 
Mongo ssh key content, the first 'AAAA' is updated to 'BBBB'

Expected results:
Step 4 should report fail instead of success since the ssh keys are mismatching
