Enable live update of Bloom filter

[satta]

It would be useful to be able to add new items to the currently running Bloom filter. A way of doing this would be to add a new fever bloom subcommand, which would allow to do things like:

• fever bloom add foo.bar to add a new indicator
• fever bloom show to display information about the state of the currently active Bloom filter
• fever bloom reload to reload the currently configured filter from disk
• fever bloom sync fever bloom save to sync the current memory state to disk

This subcommand could for example communicate with the FEVER process via a control socket.

I find sync a bit abstract. Maybe just use save and load, as they are nice duals to each other?

[satta]

Agreed. bloom reload and bloom save it is. I'd prefer to call it reload instead of load to stress that we only handle the preconfigured Bloom filter path.

I have no strong opinion on this one. But you could also argue that this restriction may be weakened in the future.
