Merge bash_completions changes from upstream
The current bash_completion contrib code in openzfs is very old, and some changes have been added since. The original repo is at https://github.com/Aneurin/zfs-bash I've been using the original @Aneurin code since my first deploy of ZoL. Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: João Carlos Mendes Luís <jonny@jonny.eng.br> Closes #10456
