Add support for custom parameters in deploy command

Add a '-p' flag that can be used to pass options and arguments to the
deploy recipe. Parameters with an '=' will be split in key/value
and added to the node['deploy']['opts'] hash. Other parameters will
be left untouched and added to the node['deploy']['args'] array.

The flag has been added to the chefrun command as well as some roles
include the 'deploy' recipe during chefrun.
Bump version
Permit attributes instead of parameters

Instead of allowing generic parameters, allow attributes, so that
chef attributes can be set. Attributes can be specified using the
notation `--attribute my_recipe.my_options.my_key = value`

This will be merged into the json file and can be used from recipes
using `node[:my_recipe][:my_options][:my_key]`
