Removing missing state file

Seems like the state file was removed, but this reference was left.
This causes the following error when adding the cluster_stats and node_stats
classes to the ceph mons:

[DEBUG   ] LazyLoaded highstate.output
local:
    Data failed to compile:
----------
    Specified SLS ceph.monitoring in saltenv base is not available on the
    salt master or through a configured fileserver
