This adds support for Dockerfile commands to have options - e.g:
COPY --user=john foo /tmp/
COPY --ignore-mtime foo /tmp/
Supports both booleans and strings.

We're hoping to add some new commands that don't have any args so this
PR will enable that by removing all of the hard-coded checks that require
commands to have at least one arg. It also adds some checks to each
command so we're consistent in the error message we get. Added a test
for this too.
We actually had this check in at least 3 different places (twice in the
parser and once in most cmds), this removes 2 of them (the parser ones).
Had to remove/modify some testcases because its now legal to have certain
commands w/o args - e.g. RUN. This was actually inconsistent because
we used to allow "RUN []" but not "RUN" even though they would generate
(almost) the same net result. Now we're consistent.

Per Erikh's suggestion at:
https://github.com/docker/docker/pull/9989#issuecomment-69832009
this PR will trim spaces in the parser to ensure that the user gets the same
results irrespetive of leading/trailing spaces.
Per @tiborvass's suggestion I added a test to make sure spaces in quotes
are not touched.
