COOK-2453: adding directory parameter to control gunicorn cwd

In some scenarios it is important that gunicorn be executed
from a path other than the current release directory. This
change adds a 'directory' attribute to the gunicorn submodule.
When set, the value of this attribute is used to configure
gunicorn's working directory.

COOK-2611 Adding queues parameter to celery LWRP

Bind celery listeners to particular queues by providing an array
of queue names to the 'queues' parameter. Defaults to ['celery'].

This change modifies the provider to use the -Q flag with the
list of queues from this parameter at every invocation. Celery
documentation states that 'celery' is the default queue name, so
this ought not to modify behavior for those currently using this LWRP.
