This PR updates Lexicon dependency to the latest version available, 3.0.6, for every lexicon-based DNS plugins. It updates also the provider construction to use the new ConfigResolverobject, and to remove the legacy configuration process.
Using the default value of 16 minutes (960 seconds) for
--dns-linode-propagation-seconds leads to DNS failures when the randomly
selected Linode DNS is not the first one out of six, due to an additional
delay before the other five are updated.
The problem can be easily solved by increasing the wait interval, so
this commit increases the default value to 20 minutes.
