This was cluttering the logs on my clusters. The log should be just in
debug mode as we do for every request/response flow.

By only handling create events, we are breaking plugins that don't
create and write atomically, like weave for example.
The Weave plugin creates the file first and later write to it. We are
missing the second part and never see the final CNI config file.

We don't want to block on accepting the terminal fd, because then
we can't detect if runc died before calling out to pass the terminal
fd. To handle this we spin the glib mainloop listening to both the
terminal accept fd and a child pid watch.

This is an optimization of our image pull code path. It's basically
how docker handles pulls as well. Let's be smart and check the image in
pull code path as well.
This also matches docker behavior which first checks whether we're
allowed to actually pull an image before looking into local storage.

This patch fixes the following command:
kubectl run -i --tty centos --image=centos -- sh
The command above use to fail with:
/usr/bin/sh: /usr/bin/sh: cannot execute binary file
That's because we were wrongly assembling the OCI processArgs.
Thanks @alexlarsson for spotting this.
This patch basically replicates what docker does when merging container
config and image config. It also replicates how docker sets processArgs
for the OCI runtime.

A goroutine is started to forward terminal resize requests
from the resize channel. Also, data is copied back/forth
between stdin, stdout, stderr streams and the attach socket
for the container.

The bug is silly if you have a master/node cluster where node is on a
different machine than the master.
The current behavior is to give our addresses like "0.0.0.0:10101". If
you run "kubectl exec ..." from another host, that's not going to work
since on a different host 0.0.0.0 resolves to localhost and kubectl
exec fails with:
error: unable to upgrade connection: 404 page not found
This patch fixes the above by giving our correct addresses for reaching
from outside.

This is not actually read uninitialized, its just that the compiler
can't detect this, but we initilize it anyway to silence the compiler.

This is what the other C code uses, and its nice to have as adding
any optimization flags enables a bunch of more warnings.

json-glib is a fine library for parsing json. However, all we need
to do is generate some trivial json output, so it is not needed.
