Various improvements to Ubuntu deployment support

The limited support for Ubuntu has been expanded

nodeconsole -t will now reuse existing tmux if started from within tmux

This will more intelligently use a detected in-use tmux session.

Improve collective behaviors

• When a collective leader goes down, provide better recovery and better ongoing monitoring.
• non-voting members will no longer be promoted to the role of leader, aligning with likely treatment of non-voting members.
• Slow dispatch operations will no longer hang up an entire confluent instance

New nodeapply command

The nodeapply command serves a similar role as updatenode did in xCAT: shorthand for a number of common operations.

Support to dump timestamped logs in nodeconsole

The nodeconsole command adds the -T option to allow writing a log with in-line timestamps.

EL9 is now supported for cloning

The command imgutil capture will now work on EL9 based nodes.

Custom roles support

Custom roles may now be specified in /etc/confluent/authorization.yaml. The roles are defined in a way similar to auth.py. This file must be consistent across a collective.
