Currently have static priority of what key is used irregardless of
whether a flag was provided via CLI or in config. This makes it
impossible to override some of the config settings. While we could try
to check if the key is provided by CLI by binding CLI flag under to
viper under a different name the same problem would occur for config/environment
variables. Fixing all of this with current set of keys is too complicate.
In this commit we revert changes from #610 and use a single flag for all types of keys.

There is a need to work with a set of Neo RPC nodes in order not to depend

Support "multi-client" mode of morph `Client` entity. If instance is not

success. Opened client connections are cached (without eviction for now).
Storage (as earlier) and IR (from now) nodes can be configured with multiple
Neo endpoints. As above, `New` creates multi-client instance, so we don't
need initialization changes on app-side.
