* Created DRBD->check_proxy_license() to do (some level of) sanity checks on the DRBD proxy license file.
* Updated DRBD->gather_data() to parse out the inside and outside ports for resource configs using proxy.
* Reworked DRBD->get_next_resource() to return 1, 3 or 7 TCP ports depending, with the new long_throw_ports parameter triggering the 7 ports.
* Added 'tcpdump' to the anvil-core requires list.
* Reworked scan-drbd to record the ports used in proxy configs. This required adding a check to change the 'scan_drbd_peer_tcp_port' column type to 'text' to support CSVs.
* Reworked anvil-manage-dr (needs testing!) to support "long-throw" DR configs.
* Updated anvil-safe-stop to check if the nodes are in the cluster before trying to migrate.

* Fixed a bug in Database->check_agent_data() where the list of tables wasn't passed in, and thus the table list wasn't then passed on to Database->_find_behind_databases().
* Started work on a new method called Storage->parse_lsblk().
