// Backend interface must be implemented to be "mountable" at
// a given path. Requests flow through a router which has various mount
// points that flow to a logical backend. The logic of each backend is flexible,
// and this is what allows materialized keys to function. There can be specialized
// logical backends for various upstreams (Consul, PostgreSQL, MySQL, etc) that can
// interact with remote APIs to generate keys dynamically. This interface also
// allows for a "procfs" like interaction, as internal state can be exposed by
// acting like a logical backend and being mounted.

// ends in '*' then it is a prefix-based match. The '*' can only appear
