203dabfb0b Place nameservers on every NIC in netplan 
netplan, like others, makes the questionable choice to designate DNS
as a NIC specific setting, despite not mapping well
to a NIC.

Since we model DNS like NTP, a global, just repeat the DNS config for
every interface.  This redundancy is fine in testing multiple
interfaces.

75add230b6 Skip API key init on checkonly runs 
Checkonly does not require API key, and makes apiclient more dependent
on material that is unlikely to exist early in a deployment.

41437c511b Fix when networkmanager breaks one of our connections 
This usually happens with ipv6 link local used
in initramfs stage, after networkmanager may
mutilate the ipv6 connectivity.

e476c7b9e6 Avoid deprecationwarning in python 3.10+ 
Newer python is not backwards compatible with
a constant.  Attempt to use new
constant and fallback to teh old one
if unavilable.

9c1e7a7142 Allow interfaces to supersede default 
In some scenarios, the 'default'
interface is overlapped by another connection, either
identical or as a superset in a bond.

Whittle down the default
interface if superseded
to mitigate duplicate interface setup.

d14d28caf8 Confirm TLS connectivity when scanning hosts 
In certain environments, Confluent may have an IP address that
is fake, but then there is elsewhere with that same IP for real.

To mitigate this, follow up basic connectivity with proof of having
an associated certificate.

ea310e472a Improve preservation of existing connections/settings 
When teaming up nics, salvage
things like dns settings from members.

When a connection already seems to exist, modify it rather than delete and replace,
for less disruption.

Running repeatedly should now be safer.

6df8170401 Draft confignet implementation 
This will team and set up additional interfaces,
but, for one, no dns.  Need to merge with deploycfg info, since
networkmanager is intent on making dns a
connection oriented thing.

6550d584a2 Give scan callers a context for tracking local interface 
When trying to leverage autodetect strategy for net config,
will need to keep track of receiving interface.  For now
only use ipv6 for this capability, as getting the incoming nic
for ipv4 would be more work.
