Rudder

If a plugin is malformed and listed in the index, the index will never be parsed and most of the CLI commands will be unusable until the repository is fixed.
This is troublesome for the user, a malformed plugin should be ignored in the index, but it should not prevent the readability of the others correct listed ones.

Also, the rudder package list should not parse the index by default.
