Baremetal should start using scheduler filters.

The baremetal driver should start using scheduler filters, particularly
the RetryFilter and ComputeFilter, as some functionality in Nova depends
on these.

However, the ComputeCapabilitiesFilter currently does not work with
baremetal in devstack due to an order-of-operations issue, so we
explicitly list the other filters that we do want.

Fix create_userrc.sh private key hang

tools/create_userrc.sh hangs in a couple of mv commands now that
private keys are created with mode 400.  mv is prompting to
override the permissions, so let's just -f it all.
