Eric Tune 64f1084c1a Rename util.config.Watcher -> util.config.Broadcaster. 
Watch is a widely used term in the codebase, which doesn't capture
the key feature of this type: broadcasting a change to several
listeners.

Eric Tune 909f82f463 Proxy: Avoid log error. Simplify locking. 
Don't log an error when Accept failed because the interface (portal)
was just removed.

Don't pass around a pointer to a serviceInfo since another thread
deletes those.  Instead, just check if service name is still in the
service map.

Delete the locking on the serviceInfo object since it is only used
by the "main" proxier thread.

Eric Tune deb101a1fb Handle error from watch. 
A watch of the API can return an api.Status rather than the watched
obejct type.  This code didn't handle that.

Tested with services e2e test (in conjunction with other PR).

Tim Hockin e925deccb0 Fix iptables for old systems 
The iptables args list needs to include all fields as they are eventually spit
out by iptables-save.  This is because some systems do not support the
'iptables -C' arg, and so fall back on parsing iptables-save output.  If this
does not match, it will not pass the check.  For example: adding the /32 on
the destination IP arg is not strictly required, but causes this list to not
match the final iptables-save output.  This is fragile and I hope one day we
can stop supporting such old iptables versions.

Tim Hockin 0c03f6e784 Enable public IPs even in not createExternal... 
This allows the proxier to portal Public IPs even if the
createExternalLoadBalancer flag is not set.

This also fixes what appears to be a bug in the createExternalLoadBalancer path
wherein multiple PublicIPs would get truncated.

Use %v for errors, tidy some messages, make error messages start lowe-case
(as per go guidelines).  Just accumulated nits.

Clayton Coleman a5462c0678 Change test cases to verify the client sends the received resourceVersion 2014-10-07 19:00:26 -04:00
Clayton Coleman 82bcdd3b3b Make ResourceVersion a string internally instead of uint64 
Allows us to define different watch versioning regimes in the future
as well as to encode information with the resource version.

This changes /watch/resources?resourceVersion=3 to start the watch at
4 instead of 3, which means clients can read a resource version and
then send it back to the server. Clients should no longer do math on
resource versions.

Clayton Coleman 4e56dafecc Introduce some default log verbosity control 
Move a lot of common error logging into better buckets:

glog.Errorf() - Always an error
glog.Warningf() - Something unexpected, but probably not an error
glog.V(0) - Generally useful for this to ALWAYS be visible
            to an operator
            * Programmer errors
            * Logging extra info about a panic
            * CLI argument handling
glog.V(1) - A reasonable default log level if you don't want
            verbosity
            * Information about config (listening on X, watching Y)
            * Errors that repeat frequently that relate to conditions
              that can be corrected (pod detected as unhealthy)
glog.V(2) - Useful steady state information about the service
            * Logging HTTP requests and their exit code
            * System state changing (killing pod)
            * Controller state change events (starting pods)
            * Scheduler log messages
glog.V(3) - Extended information about changes
            * More info about system state changes
glog.V(4) - Debug level verbosity (for now)
            * Logging in particularly thorny parts of code where
              you may want to come back later and check it

Clayton Coleman 61e3ce7ddc Make runtime less global for Codec 
* Make Codec separate from Scheme
* Move EncodeOrDie off Scheme to take a Codec
* Make Copy work without a Codec
* Create a "latest" package that imports all versions and
  sets global defaults for "most recent encoding"
  * v1beta1 is the current "latest", v1beta2 exists
  * Kill DefaultCodec, replace it with "latest.Codec"
  * This updates the client and etcd to store the latest known version
* EmbeddedObject is per schema and per package now
* Move runtime.DefaultScheme to api.Scheme
* Split out WatchEvent since it's not an API object today, treat it
like a special object in api
* Kill DefaultResourceVersioner, instead place it on "latest" (as the
  package that understands all packages)
* Move objDiff to runtime.ObjectDiff
