The field confined_target_dirs from the MIRROR_SCHEMA is
a list of strings. Those strings define the accessible target
paths for that mirror. For one target to be available for that mirror,
its path should have as a prefix at least one of the strings defined
in confined_target_dirs.
That's why when confined_target_dirs is a list with one element empty
string (e.g. ['']) this means all targets files on that mirror are
available and if confined_target_dirs is empty list (e.g. []) this
would be interpreted as none of the target files is available.
This is a confusing API that could easily lead to mistakes.
That's why it's better we promote to not set confined_target_dirs
at all if a user wants targets to be available.

Replace hard-coded logger names with __name__. For the most part this just uses
the standard conventions to create the same logger hierarchy as existed before.
The only real difference is that loggers created for printing during tests are
no longer part of the 'tuf' hierarchy.
