Log Message:
rc_net_host: make db_connect, blox_connect idempotent

Make db_connect() and blox_connect() noops if we are already connected to
the relevant database. Also, make db_disconnect() clear the db connection
handle and ticket state, so that a future db_connect() will work right.

This helps pave the way for a long-lived daemon which will run multiple
requests over the same database and/or Infoblox connections. It also
allows the database connection to be torn down and set up again multiple
times within a single session.
