* - support wildcards for namespaces
* do not annotate resource, unless policy is an autogen policy
* close HTTP body
* improve messages
* remove policy store
Policy store was not fully implemented and simply provided a way

standard client-go interfaces.
We need to revisit and design a better PolicyStore that provides fast
lookups for matching policies based on names, namespaces, etc.
