adding capability for attributes to be parsed in from profiles.yaml
set any attributes specified in profile on asset at provision
add clear_attributes to profile loader as well
use map<string,object> instead of properties to support other data types in yaml
Merge branch 'master' of github.com:tumblr/collins into gabe-extra-provision-attributes
dont use options here, its unnecessary
add test for ProfileLoader with custom attributes
remove duplicate import
Merge pull request #154 from byxorna/gabe-extra-provision-attributes
