Matthew Heon bf0d359047 Remove lock existence checks when creating pods/containers
Given that we don't have a good way of cleaning up locks, these
could potential cause issues if we ever reuse a container or pod
ID

Also changes locks dir to use tmpfs, as we can't directly clean
up locks

baude f820309413 Copy resolv.conf into container
For DNS to work properly, we need to copy the host's /etc/resolv.conf
into the container during Init().  We do this by copying it into the
containers rundir and then bind mounting it into the container.

umohnani8 74ee579375 Update kpod inspect to use the new container state
kpod inspect now uses the new libpod container state
and closely matches the output of docker inspect
some aspects of it are still WIP as the libpod container state
is still being worked on

umohnani8 622d5e3b9a Fix misleading print statement in kpod load
When loading an image, kpod load would print something like
"Trying to pull docker.io/library/alpine...", which is misleading
and makes it sound like its pulling it form the registry.
Fixed this by removing these print statements for kpod load

baude e8a32e3722 kpod exec
Initial wiring of kpod exec. We wont support the following options
for exec:

* detach -- unsure of use case
* detach-keys -- not supported by runc
* interactive -- all terminals will be interactive

Not adding exec tests as we need to think about how to support a
test that requires console access but our CI tests have no console.
