Add static hook configurations

[mcweba]

The current limitation of not having the possibility to provide static listener/route hook resources leads to projects having a huge scheduler configuration where the hooks are refreshed (re-added) periodically.

It would be useful to define static hook resources, because hooks which have to be updated (or re-added) periodically are in fact static.

When using the scheduler approach, there's also a small problem where the scheduler entries are processed with a delay on server startup. This can lead to a short time right after server startup where already requests arrive, but the hooks are not yet ready.
