Bug description:
  [Impact]
  Users are unable to enable the Ceph Dashboard WebUI without installing extra Python dependencies.

  [Test Case]
  Install and configure a ceph cluster
  sudo ceph mgr module enable dashboard
  sudo ceph config set mgr mgr/dashboard/ssl false

  errors thrown as detailed in original bug report.

  [Regression Potential]
  Minimal - packaging only change to add missing dependencies.

  [Original Bug Report]
  After deploying Ceph Nautilus on Eoan I installed the ceph-mgr-dashboard package and tried to enable the dashboard with:

  sudo ceph mgr module enable dashboard

  The following error is returned:
  Error ENOENT: module 'dashboard' reports that it cannot run on the active manager daemon: No module named 'distutils.util' (pass --force to force enablement)

  Investigating the ceph-mgr logs I found:

  2020-01-05 00:23:13.698 7f74b423cd00 -1 mgr[py] Traceback (most recent call last):
    File "/usr/share/ceph/mgr/dashboard/__init__.py", line 38, in <module>
      from .module import Module, StandbyModule
    File "/usr/share/ceph/mgr/dashboard/module.py", line 26, in <module>
      from .services.sso import load_sso_db
    File "/usr/share/ceph/mgr/dashboard/services/sso.py", line 21, in <module>
      from ..tools import prepare_url_prefix
    File "/usr/share/ceph/mgr/dashboard/tools.py", line 11, in <module>
      from distutils.util import strtobool
  ModuleNotFoundError: No module named 'distutils.util'

  I then installed python3-distutils which let me get further but the
  dashboard still wasn't starting compaining about no cert configured so
  I ran:

  ceph config set mgr mgr/dashboard/ssl false

  Now ceph status reports the error:
  Module 'dashboard' has failed: No module named 'routes'

  Investigating the logs I found:

  2020-01-05 00:30:19.990 7f663bd26700 -1 log_channel(cluster) log [ERR] : Unhandled exception from module 'dashboard' while running on mgr.ceph-mon2: No module named 'routes'
  2020-01-05 00:30:19.990 7f663bd26700 -1 dashboard.serve:
  2020-01-05 00:30:19.990 7f663bd26700 -1 Traceback (most recent call last):
    File "/usr/share/ceph/mgr/dashboard/module.py", line 362, in serve
      mapper, parent_urls = generate_routes(self.url_prefix)
    File "/usr/share/ceph/mgr/dashboard/controllers/__init__.py", line 336, in generate_routes
      mapper = cherrypy.dispatch.RoutesDispatcher()
    File "/lib/python3/dist-packages/cherrypy/_cpdispatch.py", line 515, in __init__
      import routes
  ModuleNotFoundError: No module named 'routes'

  This was addressed by installing the python3-routes package.

  Based on this I believe both python3-distutils and python3-routes
  should be added to the dependencies of the ceph-mgr-dashboard package.
