CHEF-4443 - Always save the correct run list

As per Dan's suggestions, use a primary run_list and an override, and
take care to ensure that the correct one is used to save the node.

CHEF-4927 - coerce group GID to string

To remain consistent with the way the user provider works, coerce both
new_resource and current_resource GIDs to strings for comparison. This
allows users to write their resources like:

group "zone" do
  gid 233
end

or

group "zone" do
  gid "233"
end

Without this change, every time Chef runs when a string GID is
specified, it will modify the group, which is not desirable.

CHEF-4962, knife ssh will use a cloud atttribute for port if available.

The Azure cloud can have multiple nodes behind a single ip/fqdn
with different ssh ports for each. knife ssh should be able to
run on a search of nodes and use the correct ssh port for each.
Change ssh port attribute to use cloud, reorder priority.
Refactor node search for knife ssh.
