* feat(lib): implement request weight
Replaces #608
This is a big one and will be what makes Anubis a generic web
application firewall. This introduces the WEIGH option, allowing
administrators to have facets of request metadata add or remove
"weight", or the level of suspicion. This really makes Anubis weigh
the soul of requests.

* feat(config): support importing bot policy snippets
This changes the grammar of the Anubis bot policy config to allow
importing from internal shared rules or external rules on the
filesystem.
This lets you create a file at `/data/policies/block-evilbot.yaml` and
then import it with:
```yaml
bots:
- import: /data/policies/block-evilbot.yaml
```
This also explodes the default policy file into a bunch of composable
snippets.
Thank you @Aibrew for your example gitea Atom / RSS feed rules!
