Shortpipe for roadblocks

[ginahagg]

Only files that have changed are rig_persist.erl and rig_persist_utils.erl. The rest are there due to formatting.. So ignore them.
PS: we aren't going to commit back to open source since it is too specific to our use..

Although this is our fork, not going to list any private information like JIRA ticket etc.

FILES CHANGED:
rig.hrl (formatting)
rig_sup.erl (add rig_persist gen server start)
rebar3 (update to latest)

NEW FILES:
rig_persist.erl (gen_server subscribed to be called for update event)
rig_persist_utils.erl (helpers)
