Description

There is a timing windonw during mds rejoin etc where the metadata is being added/removed and a NoneType can be returned.

Which results in brief tracebacks during `ceph fs status`

$ ceph fs status
Error EINVAL: Traceback (most recent call last):
  File "/usr/share/ceph/mgr/mgr_module.py", line 1171, in _handle_command
    return self.handle_command(inbuf, cmd)
  File "/usr/share/ceph/mgr/status/module.py", line 338, in handle_command
    return self.handle_fs_status(cmd)
  File "/usr/share/ceph/mgr/status/module.py", line 225, in handle_fs_status
    mds_versions[metadata.get('ceph_version', "unknown")].append(standby['name'])
AttributeError: 'NoneType' object has no attribute 'get'

$ ceph fs status
Error EINVAL: Traceback (most recent call last):
  File "/usr/share/ceph/mgr/mgr_module.py", line 1171, in _handle_command
    return self.handle_command(inbuf, cmd)
