Add additional `context.Context` parameters and `struct` fields to allow trace spans to be created by the `virtcontainers` internal functions, objects and sub-packages. Note that not every function is traced; we can add more traces as desired. Fixes #566. Signed-off-by: James O. D. Hunt <james.o.hunt@intel.com>
