Fixup shrink_osd[_container] scenario config

** configuration seems to be for filestore:

[ERROR]: [ceph-osd0] Validation failed for variable: lvm_volumes

** Removing `radosgw_interface: eth1` to resolve:

The task includes an option with an undefined variable. The error was:
'ansible.vars.hostvars.HostVarsVars object' has no attribute
u'ansible_eth1'

The error appears to have been in
'/home/nwatkins/src/ceph-ansible/roles/ceph-defaults/tasks/set_radosgw_address.yml':
line 21, column 5, but may be elsewhere in the file depending on the
exact syntax problem.

The offending line appears to be:

  - name: set_fact _radosgw_address to radosgw_interface - ipv4
    ^ here
