Can delete more than one profiles at one time

[unkcpz]

aiidalab-launch profiles delete now only accept one profile a time to delete. -a for delete all maybe too much but at least I can put more profiles to delete at once.

Here is how I did in order to remove the volumes created with the container, I first stop the container and remove the container, which also should be managed by aiidalab-launch profiles remove, and then runs:

docker volume rm $(docker volume ls -qf dangling=true)

EDIT: this is related to #172

I am quite conflicted about this feature. It seems like an unnecessary complication and potentially dangerous, given that the workaround is to use a simple BASH loop or xargs. Also since we renamed the subcommand from profiles to profile it also seems confusing in that sense.

For example this oneliner would delete all profiles including the volumes (after #172 is merged)

aiidalab-launch profile list | awk '{print $1}' | xargs -n 1 aiidalab-launch profile delete --purge --yes
