Set variables based on correct arguments w.r.t. name of daemonset and…

Looks like typo in daemonset

Due to 

    metadata:
      name: kured            # Must match `--ds-name`
      namespace: kube-system # Must match `--ds-namespace`

There should be 

    - --ds-name=kured
    - --ds-namespace=kube-system

As args.

Close body after error check

Otherwise it panics for nil body

`kubectl drain` now ignores undrainable things and waits for
termination, so we no longer have to do that ourselves.

Zero-valued alerts are now ignored, and the names of the first ten
blocking alerts are logged for diagnostic purposes.

Test for schedulability immediately prior to each reboot check instead
of once at startup, thereby accomodating external changes to this value
during the lifetime of the daemon.
