This commit adds two command line options, intended to allow multiple
instances of weave to run without container separation between them.
* -port=PORT makes weave bind to port PORT (an integer). Without the
option, the default value (6783) is used.
* -httpaddr=ADDRESS makes weave bind its control interface to
a different address. For instance "127.0.0.1:6784" can be used to
bind to localhost only. An absent address element makes it bind to
all interfaces. ":6784" is the default. An empty string
can be used to disable the control interface.
