3c72f9f18f Refactor slp neigh warm-up 
Rather than pulling it out at active_scan level, intervene deeply.

This fixes the problem where an ip gets used as a key rather than mac.

f50abd662a Provide analogus improvements to ssdp from slp 
Recent changes to try to make neigh table fresh and viable in slp
can also apply to ssdp.

Bring those changes forward.

1fda0e50d8 Fix stub from refactor 
foobar was a stand-in for continue to
allow refactor, and needed
to be changed to return.

c569826ff1 Improve scan result with missing neigh entries 
If no neigh table is present for
a given address, send a packet to
induce kernel activity.

Then wait for a bit over 2 seconds to allow for
2 retries (at default settings)
and then proceed assuming all findable neighbor table
entries will be found.

1c69700e1d Fix missing port 22 
Either this was overlooked or the sshd_config stopped including
Port 22.  Fix by putting in port 22.  If port 22 already existed,
sshd is fine with the configuration being configured twice.

398c8b3a71 Improve syncfiles permission denied reporting 
When a non-readable file was
encountered, confluent would
cryptically report rsync failure.

Check for the usual culprit, unreadable files if rsync fails.

Cause this error to manifest with clearer text.

c1113430a2 Pass only the name rather than full sockaddr on retire 
Followers of a server that is retiring to join the better leader
were being given incorrect format which would fail in the dns lookup.

d899cfbf1a Clean disk to install in pre 
Installers frequently fail if there's a derelict lvm on disk.

Explicitly remove the on-disk content and deactive lvm to let
anaconda work reliably.

99ba4e7765 Handle ip aliases in pxe 
Use netutil assessment of the
best server ip for pxe responses.

Using 'recvip' is too simplistic for broadcast
packets.  recvip just gets the first ipv4 address on the interface,
when an alias may be better.

netutil assesses all the possible aliases, thus has better logic and pxe.py
now uses it.

929392c746 Fix hangs on check_output 
Eventlet narrowly targets overriding
select in subprocess, to avoid rewriting adequate functions.

However, subprocess does an 'optimization' to skip
select if there's fewer than 3 pipes to juggle and no timeout specified.

Induce python to always use select
by specifying a very long timeout.

This causes confluent to be able to spawn multiple subprocesses and
not be hung waiting for input.

4ab5cac3eb Generate random serial number for certificate 
Hardcoding 0x123 serial number would cause strict clients to reject the
certificate.

While we are still not guaranteeing uniqueness, the chances of a
duplicate are impossibly small.

3b3fffb36b Note workaround for 'No data available' 
In a diskless boot, sometimes the build system
might not label the scratch contents
correctly.  setfiles can be used to fix it.

Notably, this seems to cause the overlay+squashfs to
return 'no data available' on select
calls even with selinux disabled, so it may be another
gap with overlay and/or limitation of squashfs when
queried about modification without a label.
