Option for dedicated tenancy

[tobiasg82]

A nice feature would be to allow for enabling dedicated tenancy, e.g. add an option to the config file such as "TENANCY = dedicated"

This should be a fairly straightforward fix. The following line in awsutils.py needs to be updated:

    def run_instances(self, image_id, instance_type='m1.small', min_count=1,
                      max_count=1, key_name=None, security_groups=None,
                      placement=None, user_data=None, placement_group=None,
                      block_device_map=None, subnet_id=None,
                      network_interfaces=None,tenancy='dedicated'):

All that needs to be done is add the corresponding option to the list of configuration options so that it can be specified in the config file
