Remove dynamic scoping with File from class nova.

Resource defaults are applied to all file resources
in class nova using File. In some circumstances the
scope of these defaults becomes too wide, causing
a dependency cycle. This commit removes the dynamic
scoping and instead explicitly defines the parameters
of each file resource to avoid creating dependency
cycles. Functionality should otherwise be identical.

Don't define virsh secret if already defined

We test to see if the ceph secret already has been defined before
installing the secret again.

This is mainly done to keep our Foreman runs clean, as it reports
on hosts that have had changes applied. Without the 'unless' clause
any node that has the nova compute class installed will report as
having changes applied.

Fix docstring for scheduler_default_filters param

The docstring for the nova::scheduler::filter::scheduler_default_filters
paramater tells the user to specify it as a comma-separated string.
In actuality, the param is passed into stdlib's join() function, so
it's actually expecting an array.  This patch updates the documentation
accordingly.
