Subject: [PATCH] [#645] core: Define interface of the tool for working with
 netmap keys

Announced keys of storage nodes are required for many application components
to function.

Define a unified interface for the utility for working with public keys of
nodes. Add a method to check if the key has been advertised by the local
node in the application context.
