Description of problem:
foreman-maintain uses `hammer architecture list` to verify the generated hammer configuration (username/password) is valid. however, you can construct a scenario where this command will easily fail, while hammer working properly.

We have a machine, that does have two architectures created, but those are not assigned to the organization (I have no idea how this exactly happened, but it seems possible).

# hammer organization list
---|------------|------------|-------------|------------|------------
ID | TITLE      | NAME       | DESCRIPTION | LABEL      | DESCRIPTION
---|------------|------------|-------------|------------|------------
1  | Adrian Inc | Adrian Inc |             | Adrian_Inc |            
---|------------|------------|-------------|------------|------------

# hammer architecture list
---|-------
ID | NAME  
---|-------
1  | x86_64
2  | i386  
---|-------

# hammer architecture list --organization-id 1
Association not found for organization

The last command obviously exits non-zero, as an error happened (the error is an Exception raised by the API).

Now, the user creates a  ~/.hammer/defaults.yml with the following content:

---
:defaults:
  :organization:
    :value: Adrian Inc

Which now passes "Adrian Inc" to *all* commands. And of course, hammer a l now fails:

# hammer architecture list
Association not found for organization

With this setup, "foreman-maintain health check", and any other command that needs a correctly setup hammer fails:

# foreman-maintain health check

================================================================================
Setup hammer: 
Configuring Hammer CLI...
Hammer admin password: <correct password entered>
                                                                      [FAIL]
Hammer configuration failed: Is the admin password correct? (it was stored in /etc/foreman-maintain/foreman-maintain-hammer.yml)Is the server down?
--------------------------------------------------------------------------------
Scenario [preparation steps required to run the next scenarios] failed.

The following steps ended up in failing state:

  [hammer-setup]

Resolve the failed steps and rerun
the command. In case the failures are false positives,
use --whitelist="hammer-setup"

Version-Release number of selected component (if applicable):
rubygem-foreman_maintain-0.2.11-1.el7sat.noarch

How reproducible:
100%

Steps to Reproduce:
1. have a Satellite with only architectures that are not assigned to an organization
2. use hammer defaults file to force the addition of an organization to all commands
3. run foreman-maintain health check

Actual results:
foreman-maintain health check fails with
Hammer configuration failed: Is the admin password correct? (it was stored in /etc/foreman-maintain/foreman-maintain-hammer.yml)Is the server down?


Expected results:
foreman-maintain health check works

Additional info:

* I am not sure if we should switch to another command (like "hammer user list") or make foreman-maintain ignore hammer configs in ~/.hammer (but then the user could have set the same defaults in /etc/hammer…)

* --whitelist=hammer-setup does not completely help, as other commands try to setup hammer too:
# foreman-maintain health check --whitelist="hammer-setup"
