Some parameters are broken with latest borgmatic releases

[artybdrlt]

Hello,

I've been using your role a lot lately for our servers and I appreciate your work. Thank you.

This morning I found out a problem with the latest Borgmatic version which breaks the cron task.
Basically, this role always installs the latest Borgmatic pip package (variable borg_python_packages). However, from Borgmatic version Borgmatic 1.7.0 onwards, Borgmatic parameters such as --create or --prune (which are the parameters called by the cron task) have been deprecated in favor of create or -c for example for creating an archive.

I see two solutions for this quite major issue, since my latest installation of Borg using this role wouldn't work (the cron task failed) because of this change of parameters:

• Create a new variable which gives the user of this role the ability to set a specific version of the Borgmatic pip package (such as it is done here
• Or, update the various Borgmatic parameters in the different tasks to make them compatible with the latest Borgmatic update.

Personally, as a workaround, I have written a post-task which rollback Borgmatic pip package to 1.6.5 to be compatible with your parameters. However, it can't be a permanent solution.

Thank you!
