elasticluster status

[ALX-99]

I would raise the question to implement a feature, where the status of elasticluster can be returned in reusable format. A returncode or a simple running, stopped, paused, set-up-done.

Opinions?

I will try to build a web gui and would like to display the status. This is the idea behind this question

This would be a very welcome addition, thanks!

There are two things that might be useful for this:

1. ElastiCluster supports ARA, if it is installed. That is, if import ara succeeds when the setup phase of a cluster starts, all Ansible actions will be recorded in a SQLite database file, from which a web interface could reconstruct the deployment status.

2. ElastiCluster has a Python API which you may try to use instead of the command-line client. (Note however that the CLI interface is much more tested and used than the API, so it's possible that the best solution for a web GUI is to spawn a separate elasticluster start command and read status information off the ARA database -- see above.)
