Stub for LXC tutorial
Modify lxc.created state, remove lxc.set_pass state

This commit modifies the lxc.created state to catch exceptions raised by
the lxc execution module. Additional states will follow.

If passwords need to be set, they can be done with a module.run state.
This function is not stateful and thus would run every time, making it a
bad fit as a state.
Further work on lxc refactor

Most functions are now refactored. Also added functions to match the
ones in cmdmod.py so that running commands within containers more
closely resembles running commands on minions themselves.
