truncate too long hostnames
Long hostnames can have unexpected consequences and this makes the truncation behavior explicit
This also cleans up existing truncating in AWS
How to use
A new node that uses cloud-init and has an overly long host name.
Technically the second case should never happen, because most cloud providers are attempting to block direct instance names longer than 63 chars, but rather safe than sorry.
Testing done
Test added for
..is still too longchangelog/directory (user-facing change, bug fix, security fix, update)/bootand/usrsize, packages, list files for any missing binaries, kernel modules, config files, kernel modules, etc.
