vivid's openssh and samba smoke tests failing due to missing paramiko package

http://d-jenkins.ubuntu-ci:8080/view/Vivid/view/Smoke%20Testing/job/vivid-server-i386-smoke-openssh-server/
http://d-jenkins.ubuntu-ci:8080/view/Vivid/view/Smoke%20Testing/job/vivid-server-i386-smoke-samba-server/

Both smoke tests have test cases that import paramiko to be able to programmatically ssh into the local ssh server.

The error reported is:

  stderr: |-
    Traceback (most recent call last):
      File "test.py", line 26, in <module>
        import paramiko
    ImportError: No module named paramiko

And the test cases are:

http://bazaar.launchpad.net/~ubuntu-server-dev/ubuntu-test-cases/server-tests-raring/view/head:/testsuites/samba-server/test_wbinfo_minus_u/test.py

It's likely that the error appears now on Vivid because Vivid's python-bzrlib (which is installed as a dependency for bzr which in turn is in the preseed for both tests) have a different Recommends line than the one in Trusty

 The one on Trusty is: Recommends: ca-certificates, python-launchpadlib, python-paramiko and the one on Vivid is: Recommends: ca-certificates, python-launchpadlib, ssh-client | python-paramiko
