Removes transitional v1->v2 name logic and "flat" name logic

This release removes transitional v1 to v2 node name login as well as the concept of "flat" nodes names; all node names are now "flat".

Serve v2 FQDNs in production.

This release will cause mlab-ns to start publishing v2 node names to all clients.

Bugfix for the previous bugfix release

The previous bugfix release (v2020.05.07) was trying to access the key of a SliverTool as SliverTool.key, but it turns out that key is a function, not a string. This PR corrects that. It should be SliverTool.key().name() to get at the unique string ID we assign. It also adds additional unit testing which would have caught that error before.

Bug fix for IPUpdateHandler()

Previously, the IPUpdateHandler tried to match siteinfo data with GCD data on FQDN, but FQDN was not part of the unique record key. If the FQDN changed it would find no match, and reinitialize the SliverTool. This is undesirable behavior. With the release, it now matches on the unique record key, which does not contain the FQDN, allowing the FQDN to change and be updated in the existing SliverTool.

Switch to v2 names in production

This release updates the production instance of mlab-ns to use v2 node names.

Additionally, it fixes the Ubuntu version in the Dockerfile to 18.04, since mlab-ns relies on python2, which is not the default in the latest LTS release of Ubuntu (20.04).
