Add --security-opts options to allow user to customize security configuration

security-opts will allow you to customise the security subsystem.

For example the labeling system like SELinux will run on a container.

    --security-opt="label:user:USER"   : Set the label user for the container
    --security-opt="label:role:ROLE"   : Set the label role for the container
    --security-opt="label:type:TYPE"   : Set the label type for the container
    --security-opt="label:level:LEVEL" : Set the label level for the container
    --security-opt="label:disabled"    : Turn off label confinement for the container

Since we are passing a list of string options instead of a space separated
string of options, I will change function calls to use InitLabels instead of
GenLabels.  Genlabels interface is Depracated.

Move Go() promise-like func from utils to pkg/promise

This is the first of two steps to break the archive package's dependence
on utils so that archive may be moved into pkg.  Also, the `Go()`
function is small, concise, and not specific to the docker internals, so
it is a good candidate for pkg.

Move Matches() file path matching function into pkg/fileutils

This is the second of two steps to break the archive package's
dependence on utils so that archive may be moved into pkg. `Matches()`
is also a good candidate pkg in that it is small, concise, and not
specific to docker internals

Move archive package into pkg/archive

Now that the archive package does not depend on any docker-specific
packages, only those in pkg and vendor, it can be safely moved into pkg.
