Description of problem:

Setup on a separate machine fails in FIPS mode, with:

  File "/usr/lib/python3.6/site-packages/otopi/context.py", line 132, in _executeMethod
    method['method']()
  File "/usr/share/ovirt-engine/setup/bin/../plugins/ovirt-engine-setup/ovirt-engine-dwh/core/remote_engine.py", line 83, in _remote_engine_customization

  File "/usr/lib/python3.6/site-packages/paramiko/pkey.py", line 180, in get_fingerprint
    return md5(self.asbytes()).digest()

Version-Release number of selected component (if applicable):
current master, probably for a long time

How reproducible:
Always, I think

Steps to Reproduce:
1. Setup an engine on machine A
2. Install machine B in fips mode (or convert it to that)
3. Install e.g. dwh
4. Run engine-setup choosing to configure stuff with the engine on machine A

Actual results:
Fails as above

Expected results:
Succeeds

Additional info:
This is due to a bug in paramiko [1]. Fixing it in engine-setup code without fixing [1] might not be possible or easy in all cases.
