hetzner-k3s

Add command "version" to print the version of the tool in use.

Fix: ensure that only servers created by this tool are deleted from the project. The tool now looks for servers that have a label "cluster" set to the cluster name, and ignores any other servers that may be present in the project. However it is recommended to keep a separate project for each cluster, to avoid networking issues. See README for more details.

Add more validations for the cluster name for compatibility with the Hetzner cloud controller manager.

Retry SSH commands when IOError exceptions occur.

Various improvements, see changelog in the README.

Initial release. Can create/upgrade/delete clusters with configurable HA and node pools.
