Remove an Agent from Server about gullveig

[Addvilz]

There is a pending TODO to add this feature to gullveig-util I will try to address soon. Right now you have two options:

1. Data is stored in SQLite3. You can simply use SQLite3 CLI to remove any data you want from the DB tables. This is a bit manual.
2. If you don't care about history before this - shutdown gullveig-web and gullveig-server, delete /var/lib/gullveig/gullveig.sqlite3, start gullveig-server and gullveig-web (in that order). This will wipe the local DB, of course.

I will keep this open till the CLI command is implemented. Will be like gullveig-util forget example.com and that will wipe all the data for that hostname from the server DB.

as i don't have a lot of data, i can live with remove the database and start from scratch.

Also as a sidenote, this is something I can't deal with automatically because there is no way to know - was the or some status reporting removed manually, should it have been, is it just offline, or what happened. Same with all other data - there is no way for server to legitimately know that something is no longer reported for a legitimate reason. Thus this will have to be done manually, via CLI.

manually is perfect. as you already said, an agent can be offline, then the data must still be available.
