This commit adds support to core resources to enable deferred deletion
of resources. Clients may optionally specify a time period after which
resources must be deleted via an object sent with their DELETE. That
object may define an optional grace period in seconds, or allow the
default "preferred" value for a resource to be used. Once the object
is marked as pending deletion, the deletionTimestamp field will be set
and an etcd TTL will be in place.
Clients should assume resources that have deletionTimestamp set will
be deleted at some point in the future. Other changes will come later
to enable graceful deletion on a per resource basis.

Hostname behavior across operating systems is inconsistent (Macs can
have uppercase host names, so can some other systems). In general,
always strings.ToLower(os.Hostname()).
Currently, kubelet silently ignores pods that caused host port conflict. This
commit surfaces the error by recording an event.
It also makes sure that kubelet iterates through the pods in the order of the
creation timestamp, which ensures that pods created later are ignored on
conflict.
This is the start of an uber-binary that can morph into any server. Eventually we'll want this to be able to launch multiple servers from a single command line.
It would be better if Kubernetes could be instrumented to report panics
and handled but unreturned errors in controller loops to a remote
service. This commit introduces settable handlers for HandleCrash and a new
HandleError that can be overriden to report errors to a remote service
for analysis. HandleError() in particular is for control loops that do
not return an error, and so there is no ability to report those errors
other than in log files.
ReplicationController is provided as an example.
