Arne Welzel 7eb849ddf4 intel: Add indicator_inserted and indicator_removed hooks
This change adds two new hooks to the Intel framework that can be used
to intercept added and removed indicators and their type.

These hooks are fairly low-level. One immediate use-case is to count the
number of indicators loaded per Intel::Type and enable and disable the
corresponding event groups of the intel/seen scripts.

I attempted to gauge the overhead and while it's definitely there, loading
a file with ~500k DOMAIN entries takes somewhere around ~0.5 seconds hooks
when populated via the min_data_store store mechanism. While that
doesn't sound great, it actually takes the manager on my system 2.5
seconds to serialize and Cluster::publish() the min_data_store alone
and its doing that serially for every active worker. Mostly to say that
the bigger overhead in that area on the manager doing redundant work
per worker.
