> Currently in FileAccessPolicyProvider, it is possible to specify a set of node identities, which are given access to /proxy. This works well for static clusters, but does not work so well for dynamic clusters (scaling up/down # of nodes) because we don't know in advance what the node identities will be or how many there will be.
> In order to support dynamic sets of node identities, add support for specifying a "Node Group," for which all identities in the group will be granted access to /proxy. A UserGroupProvider can then be implemented to gather node identities dynamically from the cluster environment.
